Any Character I put Charisma to 1 and for gunners I put agility to 8(with the small body which adds 1) and luck to 9 because they are the best. Also you should either get kamikazee or skilled depending on whether you want a skill boost or more action points. Those are my tips(note this is not power gaming I just love having high luck and agility).
Edit: Oh and I forgot, I always get repair to 70 by level 6 so I can get the ammo making perk. It is really usefull.
