Hey with all the headaches everyone seems to deal with when buying new wheels, i've decided that its maybe easier to go with a 15 stock rim... the only problem is I don't know what they look like b/c mine has 16"s. will all stocks fit all Gens.? (mine is the 1st Gen.)

Yes, wheels from 1st gen are all interchangeable. My rig originally had 16 inchers on it and I put stock wheels off of a 2000 SE.
