40g Where to drill....

Have a heavily modified 29 Bio with a 10 sump. Moving up to a 40 breeder with a 29 tall.
Sump is all set, i just want to be sure on the drain and return placement.
Taking all suggestions please.
I have wave makers and power heads aplenty.
1 drain and one return? If so where and where to place the wave maker?
1 drain and 2 returns? Same question.
Also, right now my return is 560gph, should i upgrade to a 700?

Thank you in advance ;)
