one thing you must take into account is the avaliability of ammo in a zombie-infested area. Obviously a gun store must be raided. a rifle that fires .22 rimfire is a must, as that ammo is sold anywhere guns are sold. with the added weight of higher caliburs, it will be hampering on long treks, with little or no sleep. also, higher mag capacity is a must when being swarmed by 10+ zombies.... what ya gonna do when your 7 round clip of .50 runs out?
as for vehicles..... 4 wheels is a bad idea, as vehicles will be blocking the street. when a zombie outbreak occurs, everyone will rush out of town, creating a massive traffic jam, and lots of food for the zombies. even a good bycicle is better than a truck, as it can be lifted over traffic jams. keep in mind that all you need to outrun zombies is a fast walk. .
stabbing weapons are a no-no, as you would need a highly skilled stab into the eye socket, or just a vicious penetrating thrust. if you can't find a good slashing weapon, then the next best thing would be a bludgeoning weapon like a bat. might take 2 swings to fully destroy the brain, though.
