I'd have to say that the survivalist forums, while usually a bit on the extreme side, do have very useful information. if you look at the principals that they use to pack/buy stuff they can be applied to pretty much any level of shall we say paranoia.
If you live in a storm prone area I'd look at putting a cage around your windows, or at least bars. That 1. stops/slows down intruders, and 2. it stops large objects from flying through your windows. Maybe you can have one made and store them in the garage and then when you need them you can just attach them over your already boarded up window.
As for alcohol, I think that while it's a comfort, out of a survivalist perspective, it's really bad. Alcohol increases your need for water AND clouds your judgement. Not a very good combo when disaster strikes.
I'd also look for an escape plan. Where do you go if you can't stay at your place? What do you need in terms of supplies? Can you use your vehicle(unlikely, but still)?
If you're going to get yourself some firearms, you would be needing something that has a lot of stopping power, but not really that much range like a shotgun. You don't want your bullets flying out the window and then hitting something half a mile down the street. The problems with weapons is that you have to be proficient. Don't even think about getting a firearm if you're not going to practice with it regularly so that you know beyond a shadow of a doubt that you'll be able to use them properly in a high stress situation.
Also, IF you purchase a firearm, are you ready to shoot another human being? Are you morally and psychologically ready to be responsible for someones death/severe injury? Or just the fact that you'll be know as the guy who shot someones relative?
If you answer NO to any of these questions, then don't get a firearm. Baseball bats and the like are in most cases just as good for home defense and they usually don't end up with someone in the morgue. That's not even talking about the possible legal complications that can come with putting a bullet in someones head.
Now, once you've set up your house for survival and you have all the necessary gear, what are you going to do about boredom? Once shit hits the fan you're going to be stuck inside your house for a LOOONG time, Nothing is more detrimental to your mental status than being bored. It will drive you crazy. So make sure you have something to do that you like. What that is, you ahve to figure out for yourself. Given that you've got a generator, you'll probably have electricity and thus(with some luck) internet, so I guess that alleviates a lot of your boredom issues, but if all that fails, get a plan.
So you have relatives in the potential disaster area? If so, what's the plan to stay in contact with them? How do you make sure that they are okay? Or if they aren't in the affected area, how do you tell them that you are okay? It seemed to me that most people in the "Hurricane Sandy thread" where worried about their relatives/friends because they couldn't reach them. So you might want to check out alternative ways of communicating.
Plan A, B, C, D.
What happens if your primary plan fails? Or your backup plan? Is there a backup to the backup plan? If not, then get one. A plan rarely survives reality unscathed, and while a plan can change, reality won't. So make sure you know what you should do, where your gear is, and most importantly, how to use it.
Many people mentioned that they had friends, neighbors, etc that had trees fall down on their houses, completely demolishing them. What is your plan for that? What happens if your house(and potentially generator) are struck out by a tree? Given that such an event would leave your house open to the elements, what is your plan for keeping warm/safe? How do you make sure that you don't get crushed by the tree? All questions that should be asked and answered.
