This may not be the disk; it could also be the controller. I've seen it go both ways. Any problems on hda?
Try adding ide=nodma to the kernel parameters. If the problem goes away, the problem is in the kernel driver for the controller or motherboard chipset.

A better way to go about this is booting off the rescue CD and doing the e2fsck scan there. Otherwise, there could be leftover problems from running the scan off of the partition you are scanning.
> Some questions:
Best advice to all 3 questions: get some sort of disk imaging software.
The disk imaging software may copy the bad sectors (i.e. sectors marked bad now may also be marked bad on the new drive), but you can force e2fsck to rescan bad sectors.
