Re: Replacing caulking
Most of the time no. The one time I did, the remover was useless.

For latex caulks, if it's separated from one surface or the other, then it's got to come out, if it's cracked in the middle, leave it. If it is in decent condition, just old and dirty, leave it. Caulking that is in decent condition can be overlaid with new caulk.
As to how to get the old off, well, again depends on the surfaces it's on. If you've got vinyl covered walls, you will have to be extremely careful not to cut them up. Fiberglass scratches easily, so use caution when working over it as well. Tile and enameled surfaces are perfect for cutters and scra-pers with the least likelihood of damage, though you still need to be careful.
As dj1 said, utility knife, single edge razor scra-per, putty knife, sharp chisel all work well. You may also want to have a paint stick, which you can use to push/scr-ape the material without damaging delicate surfaces. No matter what, it is going to take time and patience to do this project.
