Is there is a rule of thumb for how much water to feed 4-5 TPR's?
So on the UV it sounds like two of the EVO75's would be needed to get to 150watts total.
FWIW- I have a similarly sized pond, about 12,500 gal. I use the Periha UV-B Series 54W Submersible UV and it works great - and a bit cheaper than the ones you have mentioned - I do, however, incorporate a shade sail and will likely do some floating plant beds next year.
You will likely be very disappointed with only two four inch bottom drains. I have three, and that seems about right for the footprint (mine is rectangular - 12X25), but I would have liked more just for flow. Adding at least a couple mid-water intakes is a good idea-
