Firearms is really never worth it; he'd be better off just being good at either just Automatics or at Pistols and Heavy Weapons instead of meh at everything. Firearms contains too much redundancy to be worth it.
He has some anti-synergy going on with his melee skills. It's a bit complex so let me try to explain.
Why do you have melee skills? There are two reason: to hit people, and to add to passive defense.
This guy benefits from neither. He does much, MUCH better shooting people at point-blank, because (a) his melee attacks are crap and (b) he has the Firefight martial art that makes you good at face-shooting. And he has Dodge, which covers the passive defense. He would be better off ditching Clubs and just being better at Dodge. Ditto off-hand training/riposte/TWS - those are good, but you need your melee attacks to not be a joke for them to be useful. There is no circumstance where wuss-slapping people for 2P will help this guy. Better manuevers include Full Offense (remember it only impairs you from defending against melee attacks, but can be used at range), Iaijutsu (for quickdrawing grenade launchers), or Watchful Guard.
