I tend to run around the northern parts of the map at this stage, just killing the wildlife (well, that's basically what you do). After that, I'd definately want Freeze before I start in on the orcs. If you can cope with corpses, scout around (but not in) the Cursed Abbey. If you can manage zombies, go to the graveyard south west of the poor part of Rivertown. Beyond that, try doing Marcus' quests because they are reasonably easy XP's.
