You would have to try and find out what the flow rate of the overflow box is that is on the tank and match up a return pump. I like the Mag Drives myself for price and reliability.

For the second tank, I would just use it for gear and such. I don't think you could get one big enough for return pumps and plants. What shape is the tank?

Community tank with barbs? Aren't barbs aggressive? Now, freshwater tanks....its been a real long time for me so forgive me if I am mistaken.....

I like cichlids too....they make dwarf ones, right? Why not have plants in the main tank if you want them

YOu know, it is late and I had to take some serious med for a sinus infection....sorry if I sound kinda loopy.....
