I think you will have a little more head loss than that, most setups with the sump in the stand have between 4' and 5' od head pressure. The mac 9.5 will work fine but probably won't give you much room to play with. If you've got the extra couple of bucks maybe get a mag 12.

As for a skimmer all 3 of your choices will serve you well although i personally like the reef octopus skimmers the best. Vertex is a solid well regarded brand also.

As far as the required water height I've found being a bit low is better than too high. As long as the skimmer intake is completely submerged it will work fine. If you find the output splashes too much you can always fit an elbow to point the outflow into the water.
