A) Ability points are precious.
B) Sneak isn't very useful. Don't waste points in it. If you are behind someone, he won't see you even with 0 sneaking. That's all you need in the first few levels. Then you get access to invisibility.
C) Telekinesis is quite often found on rings, amulets. Again, no real need to put points into it.
D) For pickpocket (and other situational skills, like lockpicking, blacksmithing, crafting), save equipment that boosts it. Quite often on bracers and belts you can get easy +1 to those skills on each, even at low levels, so never go above skill level 3. For most of these you can also get +1 from the alignment system.
Thanks! Those are really good advices
Points in Sneak will help with Guerrilla I expect.
It should be cheaper than invi in terms of action points.
