What did the bike come with? I've not had good luck fitting front derailleurs different than what the frame was designed for. I always run into cable routing problems, interference with water bottle screws, or oddly shaped seat tubes. Then again, you may be luckier than I am.

From Specialized's website, the standard Rockhopper came with a Shimano Altus FD-M310-6, top swing, 34.9mm clamp. Find something that matches and it will work.\

The pull direction (top-pull vs bottom-pull) is more important than the clamp position (top-swing vs bottom-swing). Judging by the picture in the link above, it appears the '08 Rockhopper requires a bottom-pull FD. It's your call, but I wouldn't find it worth the trouble trying to re-route the cabling for the SRAM FD.

Not necessarily. Top-swing (ie. compact) fd's give more clearance, a bottom-swing will often clamp in a place where there is a bottle cage, pivot or oddly shaped seat tube on bikes designed for the former.
