It's been a long long time since I moved a far distance, but I have moved frequently around this area. I can give some advice there.
Stock up on tape and large black markers. MARK EACH BOX with the room you want it to go into.
Have a 'last box' - the last box to get packed and put into the truck. In it, put the stuff that you'll need the most when you get there, such as dishes and silverware enough for one meal, perhaps a pot, maybe something boxed that you can cook up easily, and don't forget the can opener! Think of all those things you need to be comfortable immediately, and put them aside to be packed in this box. This is the stuff that you'll be needing until the last minute. Towels and washcloths. Sheets for the bed. A shower curtain for the bathroom. TP. Trust me, this will be your lifesaving box.
I usually carry a backpack to work anywya, so I just used that backpack to pack all of my bills, moving paperwork, and anything *that* important that I needed to get my hands on it *now*. It was a huge help.
Don't forget the cash. You won't always have access to an ATM, so have some cash stashed away somewhere safe that you can get to in a hurry.
When you get there......one of the things I always hated was that they unpacked the boxes first, putting them against the walls, then the furniture, which ended up in the middle of the room. Argh. (For the record, I have lived in some small apartments). For the last couple of moves, I asked them to pile the boxes into the middle of the room, neatly stacked and lined up, then put the furniture around the edges of the walls. That way, I could put the furniture where I wanted it, then unpacked the boxes around them. it worked very well for the last two moves.
