My first step would probably be to try and fortify my place. The main issue, besides cost, is what material is thin enough but also strong enough that I could cover my walls, floor, and ceiling with it to be properly munitions proof? I’d probably replace the door rather than cover it, so I could pick out something that still looked nice (and of course upgrade the locks and hinges).
Second concern would be food. Doing like the mormons and eating stuff just before the due date, the problem isn’t financial so much as storage space. If I wanted my place to look more or less normal, I’d really only have about two closets worth of space to slowly build up excess cans. I’m not sure how much food that would really be.
On the porn front, I’m an artist, so I’d really probably just stock up on paper and pencils and figure that I can make my own if worst came to worst. And the paper and pencils would come in pretty useful anyways.
I’d probably want a shotgun, and some cheapo, reliable pistols that I could hand out at need to others, along with a bunch of ammo.
And then I’d probably want to enroll in some sort of first-aid course, and based on that set up a med kit. I would be more worried about wounds and sanitation than disease or pain relief (given limited supplies).
A tool kit, books on auto repair, books on edible plants, books on how to rig up stuff from random supplies, etc. would all be nice. Tarp, rope, bungie cords.
A durable car might be good, but unlike most movies I’d see it as being more likely that you’d want to keep and defend your home and establish a local community than go out wandering in the wilderness, so I wouldn’t really see a car and fuel as all that necessary.
