Well im also making one of those at the moment.
Its good to get range up for hp and for during DT.
Rock crabs/soul wars is good for XP, and since its an ice/dds pure youd probably not really need to worry about hp too much. But it dosen't mean to go do soul wars only.
I got a few sacred clay weapons for training attk/str quicker too.
You just want to keep at 60 attack and high str while keeping combat low as you can. You should get something like wc/mining/fishing up to make some money.
Quests you want done are
Death plateau, DT, MM, Lost city, And Recipie for disaster up to mith gloves. Ohh and horror from the deep.
As far as Pking, just give a few ice spells to lower their hp a bit then unleash dds specs.
