Yes, you are correct. Positive caster will help the wheel re-center itself.
As far as the turning thing, this could also be a result of caster or maybe even a little toe out. The more negative caster you have, the more the wheels will want to turn around on themselves when turning. Again think of a shopping cart wheel. If you were to turn one backwards then start pushing the cart forwards, the wheel will instantly flip back around to normal position. When you have negative caster, this is what your wheels want to do, but obviously they can't.
