No swords really do better moves: the swords (and practically every weapon aside from grenades, seeing that grenades are the only weapons you actually burn through) have five levels, the first being the one you start out with, each doing a bare 2 damage more on a move per level. The second sword can be bought at level 5, pretty cheap. The third sword can be bought at level 10, for maybe 1500-2000 or so. The fourth sword becomes available at level 15, and you have to go through a quest to get it. Same for the fifth sword at level 20. It's a lot to pay for or go through for an extra two damage per level of sword (not level of skill though). The notoriety you get from the quests will really slow all the weapons down, so I'd get them when mastered.

In the blacksmith (any blacksmith), there is a trainer there who can retrain skills. Each time you retrain skills for a weapon or post, it costs more than the last, till you've retrained so much that you reach the max cost.

I don't know whatcha mean for the third Q.

Hope that helped.
