New to 40k, need help with list

Hi everyone!
Many many years ago I played a bit of fantasy battles, and I just re-discovered the joy of these little plastic bundles of joy.

As I have a few friends who play 40k, and after I realised that fantasy battles is dead (?), I set my eyes on 40k and an old favourite - Space wolves! I've always enjoyed the painting and modelling part of the hobby a bit more than actually playing, so a lot of my choices in the list I've put together so far are based on that fact. That being said, I do want to have an at least somewhat competitive list in the context of friendly games (it's no fun being run over..).

What I've come up with so far is a batallion detachment with pretty much everything but the HQ done. I'm also at a bit of a loss when it comes to spending my CP, so any tips there would be much appreciated. As I mentioned, the choices below are based mostly on what models I like, and the gear I feel look nice, but I've at least tried to put together something that is playable as well. Any pointers on the existing list are very welcome, but I guess my biggest concern is where I should go when it comes to HQ. Are any of the characters great for the list? How do Rune priests play?

Anyway, on to the list:
