just starting to PVP

That was one of the things I wanted to know. Can I buy PVP gear? I know Still suck playing real people as my reflexes are poor.
Does it help the team to be a healer? I can use the resto druid in that case.

In short, yes it does help. Healing is a really good way to farm honor without having a lot of resil (at least in my experience). While you will still die a lot, you can at least help your team by healing the crap out of them until you get 2 shotted.
Another tip: stick to groups and don't go out on your own. You will be easy prey. Stay on def and heal the other defenders (if there are any).

As the others have said, you might just wait for Cata, but it can't hurt getting some practical experience in now. Just don't get too frustrated if you are dying alot. It's going to happen.
