Should the returns be 1.5" and the drains 2"?

The principle is correct, you may well need more outlets in the bottom due to the length and size of the tank, depending on your personal preference, outlets could be 1 1/2 or 1" .

Drain bulkheads would be 1 1/2, there is no head loss to pumps in closed loops, the head from the tank will feed more than the pump needs, you can use 2" but isn't etched in stone.

It's now 2:15am here and I need to be up in a few hours, 15 more minutes of Top Gear on BBC and I am off to bed, catch you all in the morning.
