Congrats and best wishes on moving into this new phase! Sounds like you're in a really positive state of mind about it.

Your toaster oven question reminded me of a funny thing my DH said once -- the first time we moved into an apartment that didn't have a built-in microwave over the stove: "Now we can get that toaster oven we always wanted!"

My recommendation: lots of single-portion tupperware (or whatever brand) -- then you can make a lasagna or big pot of stew and make single-size portions for lunch later in the week, or freeze them so that you're not eating the same thing all week.

Some basic tools are nice to have if you're a DIY'er. Hammer, drill, wrenches, etc.

It's great that you want to keep things simple. But another thing you might want to do is allow yourself one or two things that help the new place to feel like home. It's different for everyone. For me, I like to have plants around. I find myself compulsively buying new plants every time I move, even though it's a time to be getting rid of stuff.

Good luck!
