I have no idea how to set up this sump.

That is probably how it was set up before and would work if you did it that way again.

I run a jebao return pump. I bought 2 of them for the same price of one of the "better" ones and put the second on a shelf as a backup. I don't want to wait a week for a new pump to arrive when, not if, the return pump fails. I don't see how big your display tank is, but I'm guessing ~75 gallons? If so, the 4000L pump will work just fine.

It's actually a 40 breeder. I thought It would be best to size up on a pump in case the performance goes way down under my head pressure. Regardless, I can adjust it if it's an overkill. Only thing I'm worried about now is I have a 1/2" return line that I should probably upgrade to 3/4". Unless you think I could get away with 1/2"

I would run the 1/2" line for a 40 breeder. You could also get away with a smaller return pump. I personally would still get the 4000L, only because it's adjustable being DC. Also if you want to add a reactor or something similar down the road, the slightly bigger return pump can still be used with a T and provide enough return flow.

I didn't even look at the price- college kid here can't justify something that pricey. People seem to like this:

Jebao DCP Sine Wave Water Return Pump

What do you think? (4000)

Good pump for the price I have the bigger model on my current tank

in my own opinion, I always run a oversized pump, les heat, definitely room to expand, and also more water movement from the returns, i would also recommend if you wanna 1/2 the. I would run 3/4 to a T fitting then step down to 2 half inch returns, that way you have plenty of volume and pressure, and for a cleaner look before you add water you can paint your plumbing with Krylon fusion , totaly reef safe and is cheap!
