My best advice gained from the numerous times we've had to move: when unloading the truck, take a few extra seconds to put it in the room it needs to be in. We made the mistake of unloading things into the garage because we had to hurry and get the truck returned, then it ended up taking us months to completely unpack. If you have enough help with moving (people to unload the truck), then have yourself or someone else who would know where things belong unpack as things are being unloaded. Otherwise, the labels on the boxes of what is most important will be a huge help in getting the necessities unpacked first, then you can take things one room at a time after that to completely unpack and set up each room.
Also, as you are packing, be very selective as to what is necessary to keep (really only applies if you have any issues currently with clutter). We have a family of 8, and clutter is nearly unavoidable. The last time we moved, we filled up a really large dumpster with things to throw away, and had half of our garage filled with things to donate, and we still filled an entire U-haul after that! Packing up a whole house turned out to be the easiest way to clean my house of everything that we no longer needed.
It doesn't help you now since your moving date is so close, but we actually started packing things a month prior to our moving date. We started off with things that we didn't need every day, and stacked it in our garage until we had a truck rented. It made it easier for us because everyday life was so chaotic anyhow that it let us spread the hassle out over a longer time span.
I agree with Sherry, but rather than the Uhaul place, we just bought colored index cards from Walmart. Each card represented a different room, and we simply wrote on the card what was inside rather than writing on the box. Tape the card to the top of each box and call it good! :-)
Last thing I can think of offhand, break down your boxes as you go so you don't have a mountain of them accumulating. If you have no use for them afterward, you can either recycle them or post them on sites like Freecycle or Craigslist; someone is ALWAYS needing boxes and you will be able to get rid of them quickly. Good luck!
