yes they will
No they fit different, although mk2 and mk3 and some mk4 polo gearboxes will fit. You want an 8P gearbox.
No they do not. The Mk3 uses an entirely different headlamp as compared to the Mk4. They will only fit if you swap the front end of your Mk3 with a Mk3.5 Cabriolet. Furthermore, Hella Makes Headlamp units that look very similar to the mk4 headlamps.
You need to modify the mk4 steering wheel to fit. Get the 3.5 cabrio wheel. It looks similar and no mods required
No they can not. I made the mistake of buying some but they are completely different from MK4's so don't waste your time.
No, the floor pans are completely different. The MK3.5 will fit the MK4.
Simple answer is yes.
Yes, if they are from a GTI or VR6 mk3. Ordinary mk3 wheels are 4 bolts 4x100, while gti and vr6 are 5 boolts 5x100 same as mk4.

How do you change a power steering rack on vw golf mk4?
Yes, with a few caveats. The 1.8 20 valve turbo from the mk4 Golf is a very popular choice for engine transplants and will fit all Golfs including mk2 and mk3 models. Various VW/VAG forums have a wealth of information on this subject. SD
