only rims that fit gen2 camrys are those from the ST16x ST18x ST 20x and the latest celicas. some caldina rims may fit also but i'm nto sure. generally look for a PCD of 5x100 and an offset of +35 -> +38.
Subaru imprezas (rs, wrx etc) do have the same pcd but they have an offset of +50 IIRC. so yes you can use them as my mate did, but you will require spacers which isnt the best thing to do. your best bet would be to get some off a celica. i'd reccommend the latest model celica, be it the 15 or 16" version (16" is nicer
