I'd love to be able to fit a dozen shapes and sizes into my apartment kitchen, but space doesn't allow. In that vein, any suggestions as to which two sizes are the most used?
My thoughts: The 9x13-inch rectangular casserole pan is by far the most called-for dish in casserole cookery, followed closely by the 8x8 (or 9x9) square dishes. (The 9x13 also holds about 3 quarts of volume, so in some recipes it can be used interchangeably with a 3 quart Dutch oven, like this one.)
So I would recommend having one of each of these; they nest handily, and you can buy versions with snap-on lids, so they can double as storage when not being used to bake casseroles.
As far as adjusting amounts and sizes go, check out this post:
Readers, do you have any other advice?
