How nice to come across a couple beautiful snakes.
Gunter, my friend, I think you may find that the general snake keeping community is seriously against keeping snakes together for a number of reasons. I would guess that being a new snake keeper, you don't know this yet. I'd read up a bit more on the subject if I were you.
Concerning husbandry, there is always more to learn. You are going to want at least 2 hides, one on the warm side and one on the cold. Other than that, I would assume you know the rest since you have been doing research. Best of luck.
