You definitely want a skimmer but the throughput that the skimmer is rated for isn't going to add to your turnover rate, so you'll be better off putting it in the sump.
As for the Koralia 2 and return pump, I'm guessing that you'll loose about 1/3 of the force of the return pump due to the distance it has to push the water up (there might be a chart in the documentation included with the pump that might tell you the exact gph per distance it travels), so you probably have around 17x turnover between the two. This is great if you'll be doing fish only or soft and maybe some LPS corals. SPS needs somewhere in the 25x-30x range.

Imo it is not just flow and gph,no dead spots...
1st question is what size is the tank ?
2nd question is it a reef or fowlr?
And as for the film on the top of the water i know it will slow air getting in to the water and you need to have flow over the top to remove it.
 
Ok ok im not responding really quickly cause im using my cousins computer and hes on it all the time so im trying to reply ASAP, But I have a 55 Gallon Long thats is Goin to be FOWLR tank I would like to have some zoos though. I am planning on getting one more Koralia #1 or 2 and the skimmer. I really need the lights cause im running on some really really weak lights

Go with the #2 not #1 put 1 #2on the l/s and the 2nd #2 on the r/s
with the overflow return in the middle with a spliter to give 2 flows back into the tank.
