Bk,
What size tank is it? How long 36inches? The one halide should be fine to cover the entire tank. What bulb did you decide on?
As for dedicating part of the tank to SPS, what are you dosing? What is your flow like? It looks like two Aquaclear powerheads, which provide a very direct stream of water. You might want to look into getting Korolia's(cheap and effective), probably #2's, for water movement if you plan on keep SPS.
Another thing, if this is gonna be a mixed reef know that corals put out different chemicals and they affect one another. For example softies could put out a chemical and in turn it'll stress your SPS. You're going to need some way to take those chemicals out of the tank, carbon and a polyfilter would work since it doesn't seem you have a sump.
Try some montis when you get your halide, see how they go and get a feel for SPS before you jump into Acros and such. You're gonna end up saving yourself a ton of money by taking it slow, trust me.
Although to rockwork is nice, i wouldn't lean rocks against the glass. Personally I think it takes away from the way the tank looks.
For now try moving that other pocci up more towards the light. I wouldn't buy any more SPS until you get your new lighting in place.
In the first pic it looks like the inside of the coral is bleaching or STN'ing which is never a good thing, and probably from lack of flow and light. The second pocci doesn't look soo good either, PE isn't there.
I'd really take a step back and rethink the tank, stay with easy coral now and get a feel for how the tank works, as you progress try something a little harder, then a little harder, until you get to where you wanna be. When I started the hobby a while ago, I did exactly what I'm telling you not to do. Reason being is that when I started I was about 15-16 and didnt yet reach this site so I didn't have anyone to get advice from. So i spent and spent and everything just kept dying.
I know that was long, but I'm just trying to save you some money
