Not really commenting on the list, other than to say this... (And note that I'm much less qualified to answer these than the others who have posted)
You get used to the taste of dehydrated milk, especially if you make it slightly strong. That took care of most of my refrigeration needs back when I was single. It also made it so I didn't have to shop that frequently. If you are entertaining in the summer, buy ice (which your fridge may not be able to make anyway). If you are entertaining in the winter, try the "beer bottles in a bucket outside" method.
Something to go #1 in, with a closing top, can go a long way.
If your hair is wet coming back from the shower, try a hat or a hooded sweatshirt.
Congratulations on having a decent plan and asking the right questions in a good forum. Bravo!
Pictures would be great to see.

The best minds discuss sailing. I don't know why. It's a mystery!
