Skills to pair with priest?

[Erkni]

I've been playing PG for a week and was rolling unarmed/mentalism until about level 35 in each, but decided that Priest is something I want to try since I commonly play with a few friends. There doesn't seem to be much info or discussion on Priest, likely due to it being the newest combat skill. Any general tips or correcting any assumptions I have is more than welcome, since I'm very new.

I still want to at least be able to do a bit of damage when needed, so I'd rather not do things like Priest/Psychology. With that in mind...
...here's a few questions/concerns I have:

1. What skills do you think pair nicely with Priest?
2. Pig/Priest sounds enticing to me, but the whole beast thing is very intimidating to me as a new player. I've worked hard to obtain favor with a lot of NPCs, so not being able to talk to them easily anymore is disheartening. Mostly being unable to sell gear I find to Joeh. Is this as large of an inconvenience as I think, or is more forgiving down the line with what I hear about the Sun Vale?
3. Fire Magic/Priest sounds cool, but the high power consumption of fire magic turns me off. This got me thinking that maybe I'd get Ice Magic to use with Priest instead. Though from my understanding, Ice Magic and Fire Magic sound beginner unfriendly with how expensive they are to level. Would Ice Magic and Priest be viable?
4. Are there any belts around for priest that give them stats? I can't seem to find anything.
5. I don't know much about Druid other than the cool animal transformations. I considered looking it to pair with Priest, but it seems like you need a skill at level 50 first. Another thing is that Druids have those events they have to do, and Priests might have sort of similar mechanic later on. Little scared to pair 2 permanent things.
6. Do you think the upcoming Vampire skill will be useable with Priest? You'd think not, but Werewolves can be a priest.. The idea of a Priest/Vampire sounds interesting, especially if Vampire skills are going to be based off of DOTs or debuffing.

To summarise, a big part of the fun to me in MMOs comes from having a lot of utility in my playstyle, so hopefully someone has some tips and guidance for me.
