You have to root your phone to remove the extra verizon installed apps that won't let you uninstall them. This is a major pet peeve of mine... I shouldn't have to root my phone to uninstall apps I don't need. Recently, Verizon sent an update to my wife's phone that added Skype... she can't delete it either and doesn't use it but the stupid app runs all of the time and eats up battery life. I can feel my blood pressure going up right now just thinking about it.
You must root to actually remove them. You can hide them with launcher pro if you just don't want to see them in the app drawer.

No, you won't. There isn't an update expected in the short term... just FYI.
Most phones can take OTAs while being rooted as long as youre on a stock rom and haven't removed any system apps. This is why a stock backup is always a good idea to have. And yes you can always unroot.
Here are the files and steps to unroot your phone:

You can always remove bootstrap and stay rooted. Ultimately though, I think an SBF is the way to go. That way you don't have to worry about having this or that installed or uninstalled.
