I wouldn't use restrictor valves, all they do is put back pressure on the pump. Yes, they make the water "shoot" fruther, but it's not necessarily any faster turnover rate.
For a 120, I would say to go get a mag drive 12. Should be enough, as long as you have internal powerheads or a closed loop system.

I have the exact same tank except i have a 40 gallon sump and i have a big inline dolphin pump. I think it's the 2200 model number. I have a llittle problem running mine wide open because it moves the sand around. I put a 1" ball valve on it and i cut it back just a little bit. If i had to do it over again i would change the single return tube on eack side to a double on both sides. that would give you 4 returns and the in tank flow would be alot better. i had to put a koralia in mine to move the water between the overflows because it was a little dead there.

The size of return pump depends on what your are trying to accomplish with your sump. The sump itself doesn't require much flow since all it is is extra water volume and since you have a drilled tank you could go with as little as a couple hundred gallons an hour. Now if you have your skimmer in your sump you will want to increase your flow rate so that your skimmer has plenty of new water from the DT to process. If you are running a refugium in your sump it can be run with either high flow or low flow depending your your design and both can be successful.
A common flow rate is somewhere between 800-1200gph after headloss is subtracted from the pumps flow rate. I wouldn't bother with restricting the flow with a valve it is easier on the pocket book to just buy the correct sized pump in the first place.

+1 On that to. But a ball valve gives you more controll than gessing the return rate after head loss. If you have it right just leave it open all the way. If not turn it down its all in your hands. With a drilled tank you cant go wrong. Good luck
