I've moved a BUNCH:
If you haven't touched in a year. Sell it.
If you won't touch in a year. Sell it.
SELL everything you can (Craigslist, swap meet, garage sale) BEFORE you move. You have the free time
Extra stuff, no matter how small, the little extra cash adds up fast. If you ever need it, you can buy it later. "Are you packing plastic patio furniture? Really?" Thats what the wife asked me once and it opened my eyes.
If you need a trailer or a truck, buy one and sell it when you get there. Should be cheaper than renting one-way. Same goes for your cars if you have more than the one your driving there with. It will save you gas, insurance, etc…
Moving is a great time to purge the crap you don't really need. Save all the stuff you'll need for the first few months, buy what you need once the paychecks start coming in.
Hope that helps! I'd look at this whole thing as a great way for a fresh start[up]
