I'm sure this is a relatively simple task but I've never done it before and want to make sure I get it right. There are some holes/separation appearing in the caulk between the bathtub and the wall around it. Here is a picture:
What would be the most appropriate way to fix this? Can I "patch" the holes with caulk or do I really need to remove what's there now and reapply? What type of caulk do I need? How do I make sure there is not moisture being sealed in? Also, what is the name of this type of material covering the wall around the inside of the tub/shower area? It feels thin and kind of plastic-y. I tried to describe it to someone and realized that I do not know what it's called.

This looks like this is one of those re-lined tubs. Get that caulked in as soon as possible. I don't mean to be an alarmist, but I am surprised that the sidewalls are set behind the tub's top edge, not over the tubs edge. The way this is now, relies only on the integrity of the caulk to keep the water out from the actual tub under the liner, where it would be trapped.
Would you be able to have the tub area redone?
If that is not possible, practically any hardware store, big or small will have a mildew resistant caulk that will take care of the immediate problem. Do remove the old caulk by carefully cutting the openings that are there bigger with out scratching the plastic tub or wall liner.
