I want to bring up some alternate methods of thought, that the best way to survive the zombie apocalypse is to stay mobile and not hunker down in a single place. Here's why that it might be true.
A Zombie Apocalypse Isn't Siege Warfare
Zombie survivalists like to make a parallel between fending off zombies and medieval forms of siege warfare. At first glance, it's easy to see why they might make that comparison: you have an overwhelming mass of combatants outside your gates, but within a well-stocked stronghold, a small number of defenders can hold off almost indefinitely.
The problem with this idea is that surviving a siege puts faith in the idea that your attackers will eventually get bored or be incapable of feeding or otherwise supplying themselves and will soon stop attacking you.
We can't assume those things of zombies. Zombies don't get bored. Zombies are always hungry, but hunger won't stop them. They're impervious to disease and they will never revolt or turn on one another. They don't tire, and the chill of winter or the brunt of a storm won't faze them. There's no commander you can kill to demoralize the rest of the group. The only thing that will stop a zombie is a bullet to the head or (if you can hold out long enough), the slow process of bodily decay. And we're even assuming that zombies do decay. What if the zombie virus has some preservative quality that means the walking dead won't atrophy away to wind-scraped bones? Then you're looking at an indefinite period of zombie activity and you will never have enough supplies or ammo to survive an onslaught like that. The zombies may not get you, but you'll starve to death and won't be any better off.
Why Staying Mobile Is a Good Idea
By staying on the move, you can scavenge supplies as you go, killing zombies when it's advantageous to do so, and running when the numbers are stacked against you. You're also more likely to meet other survivors and be able to band together. It's not an easy lifestyle, and in the long run, it may not give you any better chance of surviving than staying put, but it's a way to take a more active role in your survival.
You need different skills to survive the zombie apocalypse on the move than you would bunkered down in a stronghold: you need to be in shape and you need to be able to navigate without the aid of modern devices - there's no Mapquest to help you out anymore. You need to be able to scrounge food from the world around you - whether that means hunting and foraging in the wilderness, or scavenging for canned goods in abandoned supermarkets.
The mobile zombie survivalist has more dangers to face than just zombies: they're exposed to the elements, may have trouble finding clean drinking water, and even a "minor" injury like a sprained ankle from a slip or fall could levy a death sentence if it keeps them from getting to a defensible position before the zombies arrive. Even failing that, being on the run is exhausting, and mobile survivalists may soon find their energy reserves drained when they need them most.

Mix The Two
When possible, the best survival strategy may be to mix the two: stay on the move until you find a good place to make a stand, defend it for a bit while you rest and recover from your recent journey, but get out and move on before too many zombies accumulate or before your supplies start running low.
