In a zombie Apocalypse there is no such thing as "Too many machine guns".
what if you accidentlly killed them all from to many machine guns?
nooooooo uuuuuuuuuu
What's your weapon of choice? Whatever's fucking available. IT'S A GOD DAMN ZOMBIE APOCOLYPES, PERSONAL PREFERENCE DOESN'T MEAN SHIT! (Most likely police sidearms or whatever can be scavenged from gunshops.)
What's your bodily protection? Distance! Staying away from the zombies is your best defense. This most likely means getting out into the country ASAP and setting up someplace defensive quickly. If the zombies overwhelm the cities, they'll start to meander farther and farther outward. I assume the zombies will have their own lifespan shortened, so all you have to do is survive the first exodus wave and you're home free. Might find the odd zombie here and there over the first few years but all that will survive after a point should be immune.
Where would you barricade yourself? Down-wind. Find a place where your scent can't travel far. Fire, food, detergents, shit, etc. will all carry on the wind. Hiding high in an office building or wallowing in a basement that has a chimney won't do you much good if every zombie in the area knows you're there. I'd go someplace that's foul smelling now, like an industrial area like a steel mill, refinery, swamp, cave system, etc. That way you'd have a few ways to mask yourself. And stay the hell away from places that will have attractive smells, like grocery stores, meat packing plants, food processing centers, zoos, etc. Zombies will be hanging out there.
Would you want to move yourself once in a while? Not until the initial horde mostly dies off. Once it does, a nice farm community near a big city would probably be the best place to live. If you need anything besides fresh food, take a trip into the city to scavenge.
Big group of people or small group of people? As many as possible. Increases your chances of survival during the climax of the zombie outbreak and would help improve the living during the aftermath. A larger community afterward can do more to pull a society together and offer more genetic variety (to avoid horrible mutations or sterility).
