Chances are you will need a couple different size hole saws and bulkheads as return lines are generally smaller than your drains. Your return line will depend on the size of your return pump outlet. I would think 2 - 1" drains should be enough as you shouldn't need to have more than a few hundred GPH flowing through your sump, based on a 45 gallon display. Any upgrades to flow within the display tank won't effect your overflows.
