I would recommend trading the resto shaman in for a 4 ele. I didn't use a dedicated healer until 70 doing heroics. Then, at times, I wondered why I did. I found myself dpsing with my healer and periodically healing :/

I don't know how you do movement but this was something that I didn't get the hang of until 60 + (because I went so fast with RAF).

I wish I had leveled the profs on the toon I was using as a main for my RAF. Yeah, it slows you down but a) you have some cash for skills if you don't have a main to sponsor and b) you don't have to rerun the same zones later to level them. I am talking about gathering profs. And I recommend taking those on your main, it just makes life a ton easier.
