the advantage of awd over FF is that you have a lot more usable contact patch for the drive wheels. if you are into 1/4, awd launches are a lot better than fwd. when you launch a car, the rear end squarts. in a fwd car, this reduces the load on the front wheels, therefore decreasing the traction. if you have awd, even if the front wheels lift, you still have some power goign to the rear wheels to help launch and keep traction. not to mention is is hella fun to have an awd car in the snow.

no, the Mk4 platform, Golf, Jetta, TT, and Audi A3 are the same.
the Audi A6, A4 and VW Passat are all B5 platforms.

yes, you do. depending on what mk vw you have, you can either do 4 motion or syncro, the older setup on mk2s. in general there are 2 types of awd trannies.
1) the type that are in DSM's. it attaches to the motor like a FWD tranny, but has an extra output for the rear wheels. the center diff. attaches right to the tranny and the driveshaft runs back to the rear diff.
2) the type that are Subaru's. it looks like a RWD tranny, but has two output shafts for hte front wheels right on the tranny.
