well i have a schwinn world sport and i replaced my front derailleur after i snapped the other one. i replaced it with another lower end shimano derailleur i beleive sora and ever since ive had creeking and worst of all when i switch chainrings from smaller to larger my chain often comes off. ive had it adjusted by myself and my LBS and it still seems to do this. also i have biopace chainrings.

I know you've said its been adjusted by you and the LBS, but it sure sounds like a limit screw adjustment, or possibly a height adjustment problem.

have you looked at the Park Tools tips for adjusting a front derailleur?

I agree, go with Park tools website and go through the adjustment procedure right from the beginning.
