For body armor: Leather, lots of leather. Another option denim reinforced with duct tape. Doubtful zombies can bite harder than humans so either would stop bites.

Pistols: pair of Glock 17 with 33rd mags. 2 Glocks in case one breaks or malfunctions I'll have a backup and 9mm so ammo should be easy to find.

Rifle: AR-15 I actually like the AK better because of the reliability and larger rounds but I went with the AR because of easier mag changes.

Last chance weapon: aluminum baseball bat

I'll also have a 1911 .45 loaded with Hornady Zombie-max loads and Hogue Zombie-X grips (kinda like this):
