since you had to ask that i'm guessing you've never been into a t5 before, and there's nothing wrong with that (thats how you learn stuff), but i would definitely download the free t5 service manual, it will not only show you how to do things right so you don't have to order a rebuild kit to get new soft parts, but also make it a lot easier your first time around.
hissin should have the link to the t5 service manual IIRC, or you could do a search on t5 rebuild or something like that, the link has been posted up numerous times and should not be hard to find
