Here's one of the slickest things going:

It's really all you need for a single speed conversion.

If you're looking for a fixed gear, You'll need the chain tensioner unless you have horizontal dropouts, and threaded hub on the rear wheel, a track cog, a lock ring, and a track chain. Road chainrings are compatible with track chains.

If you're lucky you can find the cog you want in a road pitch so you can use a road chain.

You just need a fixed (i.e. not a freewheel) back wheel and a shorter chain !

Talk to this guy. He knows everything about anything having to do with bikes. Also you can order parts online from him if you need parts and dont live in the same state as the shop, or you can just call him or email him and ask questions. He is sooo in love with bikes, that he will help you even if he knows it is no profit to him. Everyone who races or mountainbikes alot in nj know the bike stand. :) I gaurentee you he can help you.
new crankset
new rear wheel
remove both derailleurs
shorten the chain as needed
simple
For a bike you can use either as a fixie or single speed, you need a flip-flop hub. You can get a wheel built up with a flip-flop fairly inexpensively. This allows you to run fixed some times and ss other times. In the same ride even, just flip the wheel over and go. Of course you will strip all of your shifters etc. Use the middle of your front 3 rings and take the others off. You will need shorter chainring bolts.

You do not need a new crankset, you can use the one on your bike.

It depends on how elaborate you want to go.

Chain tension

If you have a frame with horizontal dropouts start with that. if you don't you will need a tensioner or and eccentric bottom bracket shell. You could just shorten the chain and drop it on the right sized sprocket to get the tension but this severely limits options.

Rear gear/s

You can leave your cassette on (which is helpful working out your best ratio) or remove all but one sprocket and space the rest out. If you fit a single speed hub with or without a freewheel, (I recommend a freewheel pedals hitting the ground in hard corners = gravel rash). you may need to reset your rear fork width for a narrower hub.

Chainring
You can keep your double (or triple) chainring or change to a single.

Derailleurs and shifters/brake levers

You can ditch front and rear derailleurs (of course) and the shifters if they are separate. If you have sti shifters you can remove, just the cable or replace with brake only levers.

Summary
It can be as simple and cheap as shortening the chain or as elaborate and expensive as you like.
