Let's just call you "One". Your lighting is fine for many soft corals but depending on the type of anemones you'd like to keep, your lighting won't be enough (ignore this comment if you're talking about mushrooms). I think you have plenty of rock for both tanks.
As for a return pump, I'd go with an external and bigger than you think you need. You can split the return a couple of times thus cutting down or elimanating the need for power heads.
