1. Replace the front small cog. To what?
2. Replace the rear cassette. If it has 11x32 now what else is there out there and will the shifting be the same as it is now which is sweet?
3. I guess a wheel set. I am not a weight weenie but I do want a bike that I can climb with and it's not this bike right now although I do like the bike. I probably am tapped out money wise now with what else is going on in my life and some trips I have planned so wheels if that helps would be on for next year's agenda and or over the winter.
4. Does anybody put a triple on a road grinding bike and or with the compact crank on this bike does it have almost the same gear inches that yoou would get on a triple. How much would a triple cost?

1) You can only go one tooth smaller to a 33 by buying a TA Specialities ring. To go smaller requires switching to a crank with a different bolt circle. See the 46/32 Crankset or Old Guy's thread. Probably $300.
2) You could switch to a cassette with a 36 tooth big cog and it would probably still shift OK. It's out spec but people have been pushing 36s on max-32t derailleurs for a while. You could improve things a little with a 9 speed mountain derailleur or one of the 'trekking' models which should have a longer b-knuckle than the 105. Any bigger and you'd need a Wolftooth Roadlink to move the derailleur further away from the cogs.
3) Yeah, you could definitely save some weight here. Switching from the stock rims to DT 460s saves you 200g right there, and then at least go to butted spokes. Less spokes (on a different hubset) or alloy nipples are options too if you're OK with the tradeoffs. Plus you can switch to tubeless if you like. OEM tires are usually heavier than aftermarket so that might be a good place to start, but I'd pull one of the stock tires off and weigh it first. $150 for tires? A lot more for wheels.
4) With the range of 11 speed cassettes triples just aren't that popular anymore. Dropping triples means one less shifter to make and stock, and from a technical standpoint it's a little easier to engineer the front derailleur to deal with only one shift. But set up right for the right conditions than can be pretty great. You'd need a new crank and left shifter at a minimum and probably a front derailleur too.
I'm going to guess that seat post is pretty clunky and that's an easy thing to upgrade.
It all comes down to power to total weight, so dropping 2 pounds off of 225 pounds of bike and rider will save you less than 1%. Training and losing 2 pounds off your body will give you the same effect, plus the bonus of any extra power gains from your training.

Fortunately your Tamland has "external bearings" which are very standard and you should be able to find a new crankset with a compatible bottom bracket. Dropping from your current 34t small ring to a 30t ring will be about a 12% lower gear ratio. A slightly smaller jump than going from your 13t cassette cog to the 11t cog...
Here's a link to what I was thinking would work:
https://www.bike24.com/p2208747.html
There are other brands available as well.
Another route would be to go to a standard mountain double crankset. With mountain cranks you'll be able to get MUCH lower gears but will sacrifice on the high end as the large chainring will be small by road standards. Two problems:
1. If the crankset has an integrated bottom bracket axle you'll need spacers for the bottom bracket as mtb bottom brackets are a bit wider than road. Any good bike shop will have these.
2. You'll need to make sure your FD will have enough "throw" to reach the outer ring. The wider BB will push the chainrings out a couple mm.
The same issue would hold true if you went to a triple crankset - the throw to the outer chainring is farther so you need a FD which is designed for a road triple. The new compact cranksets with 16t jumps along with 11spd cassettes provide much wider gearing which is sufficient for most bikes and applications. The result is that fewer and fewer people are using triples.
Other options such as going to the new mtb cassettes with 42t and larger cogs will be expensive for all the new parts.
One caution: Shimano 11spd road (105, Tiagra, etc) shifters do NOT work with the Shimano mountain rear derailleurs. This is because the cable pull is different. So trying to mix and match road and mountain parts is not straight forward. SRAM 10spd is compatible between road and mountain, but this is not the case with 11spd.
For ideas on what will work for a triple setup, check out the touring bikes which are setup with triples.

Greg

Neither year had tubeless ready rims either.
Bike24 is sold out on the FSA cranks, but I see them listed on eBay. It's worth noting that they use their own unique bolt circle so finding replacements rings could be a pain at some point.
I'd point your budget on things like getting the right seat, good fit, food/water setup dialed, and those things require putting in some miles. I could see making some dumb mistakes, like buying a lightweight zero-offset seatpost and then realizing you can't push your Brooks saddle far back enough.

But are you sure they aren't tubeless ready? My 2017 Tamland 1 is, and it looks like it has the same wheels as the 2016.

Thanks Greg(NoCoGreg) for this info. After reading DrWelby's post I think I am going to wait a month or so and see how much my fitness level improves. The crank option that you posted though looks sweet if I can't still climb well after that time though. Not being a bike techy though do I still have to find a different bottom bracket that will match/work with that crank or will my current bottom bracket work?
Thanks

Yes, the new crankset would also need a compatible bottom bracket. Raleigh doesn't spec the maker of the crankset nor bottom bracket so my guess is it's a no-name maker from China. It might be compatible with Shimano or SRAM or neither, you'd have to go to a local bike shop (LBS) to get a determination.
...
Next least costly will be an inexpensive 46/30 crankset and bottom bracket. The OldGuy thread mentioned above was a more difficult situation because his bike has an obscure bottom bracket while your bike has a very common threaded bottom bracket with external bearings.
