What sizes should my return and drain lines be?

So yesterday I started setting up the 180 in the office. I drilled a 1/2 hole into my wood floor without my wife's knowledge (I don't know what I am gonna do with those holes when I sell the house) Anyways, before I drill couple of more holes..What size of pipings should I be running from the tank to the sump. My plan is to have the sump and all my equipment running from the basement. The basement has a ceiling of 12 ft., so I think the pump (sequence dart) that I ordered is underpowered. Might either sell it or order another one of the same and run it parallel.

The tank comes with 2 set of fittings. One has 1 3/4 inside diameter which I presume is the drain. The other has the 1 1/4 inside diameter.

Those should be fine. You don't want to blast water too fast through the sump or your skimmer won't have any time to do anything. You are correct that the larger one is the drain and the smaller is the return.

Assuming it's standard, I believe the return is 3/4" pipe and the overflow is 1". If you can find a bulkhead for the drain that has a 1 1/4" MPT, you can use 1 1/4" pipe on it, but those seem to be harder to come by now. Newer ones are off by just enough to make it impossible to screw a 1 1/4" FPT onto the end.

If I were you, I'd keep the Dart for a closed-loop circulation system and get a pressure/high head rated pump that's going to do a better job of lifting the water out of your basement up to your tank.

Just for future reference... next time drill the hole in the wall and go down inside the drywall. When it comes time to move/repair, it's MUCH easier to fill a hole and patch/paint drywall (especially for those that paint before they sell anyway).

You know I thought about doing that..But I didnt' know how many 2x4s at the base I had to drill throught, and I would think that it would be hard to drill for 2 inch pipings...

I just got through doing the same thing (opened up a hole in the wall and cut a hole through the 2x4 sill plate). I drilled four 3/4" holes in a rectangle, then used a sawzall to cut out the rectangle of wood. This gave me an almost 14" x 2.5" hole. Should be enough for my closed loop in basement and the drain/return lines.
