Crowbar, your standard melee weapon for when the ammo supply starts to run low.
As for primary, screw the shotgun, I'd take an AK-47 or other automatic rifle designed to deliver each bullet with a punch. Enough force to rip open a zombies head in one shot, used on single shot it has more ammo per clip, greater power, and similar accuracy to a shotgun.
Of course, seeing as I possess neither a crowbar nor any gun I'd probably end up using the nail-removal end of a hammer.
EDIT: actually an axe would be more effective than a hammer, though I'd still keep the hammer handy as the axe may get stuck in something (or what was someone.)
Also, considering things like nemesis, I'd probably want a high-powered sniper rifle, assuming I could learn to use it. Screw close quarters with that monster, I'm taking him out from half a town away... preferably while supported by tanks and with the army clearing up the remnants of the zombie infection.
