having lived at an apartment during school, i can second that list of things listed.
and, you can never have enough TP. I used to keep a pack in my room for when you don't realize you're running low and all the sudden you're out.
paper towels are also key.
also, along with a dust pan and brush, a wet swiffer thing works really well, especially if your floor isn't all covered in carpet. I don't know how many times that came in handy. also, i'd suggest investing in a small vacumn cleaner. my college had them available to borrow, but they always seemed to be loaned out when you wanted to borrow it. just a little 20 dollar one works nicely.
i also suggest the tool kit.. make sure it has a hammer, pliers, both types of screw drivers, and maybe even a tape measure. my roommates and i used to like to move our furniture around and we never had a tape measure to see if it would fit and it ended up taking like 5 times longer than if we would have measured.
also, don't forget the power cord to your computer. I know it's a simple thing, but you'd be amazed by the number of people who forget it. people have their computers set up at home, disconnect the power at the back, pack up the computer, and leave the cord plugged into the surge protector. I did it myself sophmore year.
also, i'd suggest picking up some of the 3m command strips for poster hanging. I believe you can get a pack of 12 at walmart for like 2 bucks. they work so much better than the putty, and don't gunk up the back of your posters or the walls.
another thing... hangers. i know a bunch of people who completely forgot them. (my roommate being one of which...)
and yeah, a hand truck works wonders. my parents always brought a hand truck and it was such a hit, everyone on my floor ended up using it.. and of course my dad being the social butterfly that he is would even carry the stuff in for the people while carrying out a conversation and meeting new people.
definately get a nice sized coaxil cable for a tv if you are bringing one. don't forget the cables to hook the dvd player up to the tv either. also, extension cords come in handy so often... as well as surge protectors. you can never have enough. my roommates and i invested in a 25 foot coaxil cable during soph year and everyone laughed at us for getting such a huge cable. when we moved into our apartment the next year, the place we wanted to put our tv was on the complete opp. side of the room as the tv jack.. so it came in handy because we could just run the cable right under neath the carpet while everyone else was stuck having their tv at the same spot
oh another thing, if your kids are hanging curtains, i'd suggest getting the springy curtain rodes.. because you normally can't drill into the walls to use regular ones. make sure you know the width of the window prior to purchasing.
