Bless is a VERY usefull skill as a Warrior. It can also bo good to have Aura of Guarding as a Warrior. Unless you use charms also the Magic Shiled can be usefull. Expertice in the type of weapon you want to use should be used. Restoration is also good if you run out of healing potions.
IMO skills like pickpocket and picklock is just a waste of skillpoints. If you want the dagger for the holy weapon see if you can find a item that gives bonus in pickpocket and picklock. There's a risk that you won't find any such items though.
