There aren't really "collars" unless you'd specifically like to add one to your character. The translation devices operate on some kind of microscopic sciencewank explanation, so they aren't actually visible. Also, the fact that some of them don't work means people who don't want to use them don't have to.
As for rules... Basically, more-or-less normal canon rules apply for each species, but feel free to wing it. You can unite as clans and try to escape, or go for an every man for himself approach and try to win. Up to you.
