Not to complicate things further, but... it may help to think about how much you DON'T need to pack. Often, the move-in and move-out schedules in stock (and regional company housing, for that matter) are very tight, and the last thing you want to do is spend your first and final days wondering if you'll ever finish unpacking (or stuffing things into your car.) Also, know you'll probably have wonderful opportunities to collect the perfect sweater, handbag, work pants, tool belt, etc. while you're there, and will definitely want to bring it home with you... so allow yourself the space to bring back a great find, that also brings back great memories!
After spending about half of the last five years in company housing or traveling with a show, I've learned to pack so I can leave something behind or toss it out. In my case, that means ratty workout clothes, T-shirts I don't care about, and (occasionally) running shoes that should be recycled anyway. They're useful while I'm there, and when it's time to start packing, I drop off anything really useful at a Goodwill, and toss out the rest. (If you're responsible for any cleanup before you leave housing, an old T-shirt can be extra useful!)
It sounds like you'll be sharing housing with some colleagues, too - have you connected with anyone about kitchen supplies? Depending on the kitchen setup, it might be really helpful to sort out any large purchases or appliances. Does someone have a George Foreman grill they're comfortable sharing? Does someone have a knife set? What is provided, and what do you and your housemates feel is important to make the kitchen your own for the season? (A blender, for post-opening margaritas? An mini outdoor grill for s'mores?)
More than anything else - congrats on the gig, keep us posted, and have a fabulous time!
