Ok, so in short: the states can do what they want as long as it doesn't violate federal law.

Yep. In all things where there is no federal law, the States are in charge. I mean, I'm sure there are probably some odd little exceptions here and there around the country (like maybe some State-Indian tribe compacts or something like that), but for the most part the States are the sovereign in all areas where federal law doesn't govern.
