I did this upgrade on my 2003 Trek 4500. In addition to the disc brakes (Avid BB7s are highly recommended) and disc-compatible wheels, I believe for a 2004 Trek you will also need a special adapter for the rear caliper mount (as I recall, 2005 and newer models do not need this adapter). Replacing V-brakes with discs will run you about $300 for the brakes and wheels, plus some shop labor if you are not "handy". You can use your current V-brake levers.
Expect only modest improvement in stopping power over properly adjusted V-brakes when dry -- but significant improvement under wet conditions. You have to decide if disc brakes are worth it to you -- I believe the 6700 is worthy of the upgrade.
