Just had this problem with my 01 Grand Prix tonight. I hit the crap out of it (the rotor) and it still would not come off. Turns out that having the emergency brake on was stopping me. I chocked the weels and took off the e-brake and they came right off. Hope that works for you. It seems that this answer is not found on any of the pages I've seen so far.

Front Rotor Minimum Thickness after machining the rotor is .996
No model was given however the most popular 2001 Saturn was the L-Series which takes 19" on both sides front and if applicable, a 13" rear. See related link to lookup correct sizes and some options.
The S series Saturn does not use a timing belt; all four cylinder Saturn's use a timing chain.
