I'll throw in my 2 cents here.
I agree with the color keystones. It is really a waste, and it just draws attention to the plate in general. I personally want those wall plates to disappear as much as possible. Having orange, or blue or red keystones just draws attention to them. You can always get clear labels and print something for the plate, but you really only want to label them Cat6 -1 and Cat6 -2, RG6 -1 and RG6 2. To specify anything more is also going to be confusing when you end up repurposing the plug to do something else.
I'll also recommend that you run more CatX wire while you can. Two is not going to be enough in some locations. Better to run three or even 4 to each location IMHO. You might be thinking 1 for phone and 1 for data. But what about extending video signals (RGB) or IR repeaters, or audio signals, etc.
With todays houses becoming more media friendly, I think you will be happier if you run more wires. These extra wires can easily becat5e wires if you want, but better to run more than you need while you can. Since you can already find uses for two wires, you need to run more for the things you forgot about or that weren't practical now, but will be in 3 years.
I've run 6 cat5e wires to my Den, and I currently use them all. Three to the TV (one for the IR repeater system, one that extends serial control for the TV, one network data which is hooked up to a thin client attached to the TV, a network cable that I have my wireless AP attached to, one network cable behind the couch where I have another thin client hooked up, and one phone). I realize my situation is probably a little more extreme than most, but I only added the IR repeater system 4 months ago and the thin clients 1 month ago. So my system is constantly changing and I'm extremely glad I ran extra wire that I thought I would never use.
PS - you don't have to use one of these overpriced "horizontal" patch panels because your space is only 14"wide. You can get any regular patch panel and mount it horizontally. So you can easily get a much larger patch panel for about the same price as those "other" panels.
