2, I'm guessing the context for shield+penance talk is when the tank (or whatever) has taken a spike of damage. The shield provides instant protection (buying you a little time), and you get a haste buff which penance does not consume. So it's a good combo right after spike damage. I commonly do shield+penance after Maexxna's webspray for instance.

3. I almost always cast PS on the tank or myself. It is sometimes a wipe-preventer when used on the tank especially, and so yes, I think that means I use it as a kind of bubble. On most dps, it won't save them in many cases, and they are usually not as crucial either, so I tend to save it for the tank or healers almost exclusively... Maybe others are different, though.
