See http://www.ttcautomotive.com/English/onlineorder/product.asp to download a FREE service manual for T5 or Tremec 3550
You will need the Adobe Acrobat viewer which is also a free download – http://www.adobe.com/products/acrobat/readstep2.html
See http://www.hanlonmotorsports.com/ or http://www.ddperformance.com/index2.htm for parts
http://cartapes.com also has a video on how to rebuild your T5 or Tremec. It costs less than $20, and is worth every penny of it.
I did a Tremec 3550 rebuild, and it wasn't that difficult. The video was an immense help, and I would recommend viewing it. At $20, it will give you an opportunity to look and decide for yourself if you think that it is something you want to try to do.
You will also need a magnetic base and dial indicator to measure the endplay ($20-$40). http://www1.mscdirect.com/CGI/NNPDFF?PMPAGE=1290&PARTPG=NNLMK32
The tricky part is that you will need some shims to adjust the endplay in the two shafts: the new bearings will change the clearance. There is no way of telling what it will be until you get to the point that it is time to measure and check the clearances. Halon has the individual shims if you can wait for them. If you can't afford the wait, the auto parts store can sell you some shim stock and you can make your own, or have a machine shop make them for you. The shim stock comes in brass (easy to cut) and steel, in varying thicknesses. That's where the dial indicator & base come in - there is no way to get the clearance right without it.
Getting the car jacked up high enough to get the trans jack in and out from under the car was somewhat challenging. Since I didn't have a helper, getting the trans out of the car and back it was one of the more difficult things about the job. I built a trans jack out of 2x6's, some angle iron and a $25 floor jack. If I hadn't done that, I would have needed a helper or to rent a commercial trans jack. At 100+ pounds the Tremec 3550 was far too heavy for me to lift by myself.

I agree with the advice of looking at the video and seeing if you want to get into this project.
Call hanlon motorsports and see what the estimated cost to repair it is with just the basic rebuild kit. They will give you a number over the phone.
If it's under $500 i would let them or someone else qualified to do it.

actually the 3550 and the tko from that period are two different beasts. The 3550 utilizes stock spline count for the input shaft and output shaft, and the tko uses a different spline shaft that requires a different clutch disc, and a different driveshaft yoke, and has other upgraded internals. the two are not to be confused with each other in case you're gonna do the rebuild.
