The FAQ is great, but doesn't really answer his question. Like most FAQs, it covers talent builds at level 70. He's level 20! I felt somewhat lost with talent points until I hit level 35 or so. My tree was an absolute mess, with choices made based on 'that looks pretty good, oh so does that!' I had a few points here, a few points there, but there was no cohesive plan at that point. Ultimately I read enough things about the different talents where I was able to figure out what I wanted and respecced
That said, if you look at the different builds suggested in the FAQ and think about what you want down the road, it will help you choose how to progress moving forward. If you're looking to go holy, your next five points should definitely go into Divine Intellect. The five points after that should go into the next tier of the holy tree (can't remember what's there at the moment).
At level 20, I think the choice of weapon is not yet super-important. If you've sunk points into Redoubt, however, then those points are wasted if you're using a 1 H.
