Congrats on your purchase.
D4D, is spot on with the insulation, if you can't get hold of any quickly use newspaper, about 5 or so layers will do the trick until you can get hold some proper stuff. It also comes in handy for starting a fire
Use to use newspaper in the front of my jacket when I rode my motorbike in winter
Same as you, the non slip stuff, we have the metal plates/bowls and cups which get wrapped in tea towels and thrown in the cupboard. Same with the pots & pans and stuff.
Non perishable food is left in the green shopping bags and placed under the seats and in other cavities. You'll be surprised how much gear you can pack into them
Hope you shake down goes well, yeah, you'll have to post pics on your return.
Happy camping.
