I'm not a big fan of acrylic tanks because they tend to scratch very easily. Also, custom made tanks in exotic shapes, like that 230 Gallon Wing Bowfront, tend to have stratospheric prices. That may stop you from doing more than look.
I agree with Eric, I would choose a berlin type sump and a large powerful skimmer. Generally when buying equipment, you want something rated for a tank size of double the tank. Manufacturers tend to be "very optimistic".
I would recommend going with a serious external pump, such as an Iwaki MD100. Pump mounting is critical to keeping noise down. I have never found the quite one pumps to be that much quieter, but that was with the older models. Keep in mind that a large tank is going to require that you move large amounts of water. Expect some noise and consider that when you locate the tank.
Omit the UV light and pump. UV is of limited use on reef systems. Only add it if you have a very specific problem to deal with. In addition, if you are going to add one, you need a much more powerful UV unit since this is a SW tank.
As Eric points out get a beter skimmer. Make sure it's rated for a tank that is double the size you plan.
On the chiller. It's not a bad thing to have, and you sized it correctly. I would reserve a place for it, but don't add it until you really need it. I have one on my reef, and it seldom comes on.
The lighting you plan is good for zooanthids, polyps and the like. If you want clams or SPS corals, you might as well go with MHs. Use 250w or 400w MH depending upon the depth of the tank. I tend to like the 250w since the heat output is less, and the bulb selection is greater.
When you get into pumps for circulation the Vortech pumps or the Tunze stream pumps are usually considered better than the Korallia pumps, especially when used with a controller to give you random wave patterns.
Additional items to consider -
You might want a controller to actively monitor and control the system.
You might want a automatic top unit to keep the water level and SG more constant.
