First Full Bike Build

I've decided I'm going to build up a new SS this summer. My motobecane just isn't cutting it and needs to much work and too much money.

I just bought a Lemond Reno frame off ebay for a pretty good deal.

My next question is how do I go about finding a fork to buy? Carbon fiber isn't all that important. Should I look for a threadless 1 1/8 steel fork? The rake of the original bike is 45. A threadless fork recquires a threadless headset and stem as well, right? Im sorry....veyr basic questions.

Okay, first step, ensure it really is a 1-1/8" and not 1" head tube. Measure the diameter of the opening of the head tube (either top or bottom), it should be 34mm (not 30.2mm).

Steel fork would be fine, but you can find inexpensive carbon fiber forks, too. You could put a want ad in your local Craigslist and see if someone has a 1-1/8" steel fork laying around (after upgrading to CF); just make sure the steerer will be long enough (his/her frame should be as big or bigger than yours, but measure to be sure). As for rake, it's best to stick to 45mm as the frame was designed for it, but going to like 43mm won't be noticeable (if you notice anything, it will be greater stability in keeping a straight line).

This might get you started:

Not really, some MTB stems may be stonger, but since it'll be going on a road bike, it doesn't really matter. But you're right, most road stems are going with 26mm and MTB w/25.4mm. If you do get a 26mm stem, you can use a pre-made shim or make one yourself (a strip of an aluminum beer/soda can wrapped around the bar is just about right).

I have this stem on my mountain bike, which has a 25.4mm clamp and is surprisingly (almost alarmingly in my opinion) light for a MTB stem (same weight as the road version, just a different clamp):

another question:
this is the frame. does it look like it has headset races in and even possibly a BB? or is that just some black covering.

Hmm...it looks like headset cups, but if that's all it comes with, you're probably better off getting a new one rather than trying to find matching races and getting bearings. Don't know why the bottom bracket shell has that black end, it doesn't look like a bottom bracket, unless they're outboard/external bearing cups--it's hard to tell. Just wait till you get it.
