My 4BTA has a power steering pump with 3 ports.
One being high pressure the other two being low pressure?
I know what to do with the high pressure, but not what to do with the other two.
I know one should be the return so:

Could I go PS pump high pressure port-->hydro boost-->steering box-->reservoir-->larger low pressure port(return?)
The run the low pressure return off the hydroboost to the remaining port on the pump?

Yep..

One supply, two returns, one each for brake booster and power steering box.

IIRC, you're right on the high pressure: goes from pump to brake booster and another line takes high pressure to the steering gear.

Right on.

I had to use a T before the return on mine to take the return from both. I'm not sure how correct this is to do but I figured the pressures would be pretty close.
