Hard to argue with any of the above. I would just emphasize what has been said. (And here I'm assuming a limited budget). What will you do the most of? Don't just go off buying tools. Start witth what jobs you need to get done and in what order.
For HD, the shotty is fine. You're covered. If you can CCW do so. Even if you don't have a pistol now, take the class and get the permit (it can take weeks) so its in hand when the money fairy visits. If you can CCW, I'd start with the pistol, its something you can and will use every day. I like glock as they are monkey simple and always go bang even if you're a clean it twice a year kind of guy. However, any of the usual suspects will work. Also don't overlook snubbies. Me, I like 1911s (gasp!, yes I admit it), but not for CCW. The reason is that I want simplicity in a crises gun. No saftey, DAO, point and click. The less there is to go wrong, the less likely I am to FU.
As far as hunting, the .308 is a good caliber. I use a Ruger .270, but I should have gone .308. My reccomendation (assuming you're right handed) is a Savage 110. They are the most accurate out of the box rifle out there and at about 3/4 the price of the competition. Don't believe me, research it. Try GunBlast.com, this site and many others. If you intend to customize, a Rem. 700 is probably the way to go, but out of the box, my money is on Savage.
An AR is a toy, and great for Zombies. Its the last rifle you need. I own one and love it. Need it, well, for large values of need.

I have a DPMS Sprortical I paid about $650 for. I'll end up adding an extra $150 to that to get it where I want it. Then there was the Eotech.

Still a great rifle. Also check out AKs. Cheaper, sturdier and good enough for pigs, just a 200 yard gun. Bear in mind, an AR-10 IS NOT interchangeble with .556 uppers. It uses a different lower. You cannot interchange parts with ARs and the mags are pricy. Still a good gun, and with a five round mag you have your hunting and SD rifle in one. Just budget an extra 3-4 bills to buy lots of mags for your gun as they are proprietary and could dry up.
Good luck and rent before you buy if you can (probably harder with rifles)
