According to EIA/TIA specs you SHOULD use adapters.
Yes this is also why POE usually runs on the 7&8 pair. It is possible to slap a phone cable into a data jack and this would prevent any issues getting on to the center pair. Even though it is just as easy to be off a pin between some plugs and jacks.

BTW - I've had ringing and data on the same cables for years. No problems. Of course I'm not in a high production environment - but that's not what igadget is talking about either.

I agree with the "holy jack" arrangement myself, it means less mucking with the internal wiring. It also means that anything dangling off that gets damaged can be replaced. In my case it also gives me flexibility for the use of jacks in a given room. Another benefit for keeping the jacks holy is that I can move to Gig-over-copper by only swapping out the switch since the runs are so short.
In answer to the other questions, I have a 24 port 2u 5e panel in what will pass for a comm closet for both data and phone cross connects. The space is about 2.5' square and only about a foot deep. The switch is a desktop model so it should fit without issue on a shelf I'm putting in. The switch vents through the short ends, not front to back. Right now the panel wrapped up and pulled to the side so that a power duplex can be installed for the UPS and for what ever the home owner is going to be using for video distribution.
Also thanks for the link, Skip, those will take care of the 4 pair spilt. The one data and two RJ11's was more hope, than based on what I'd likely to get.
Edited to thank Skip for the link.
