Cisco 9900 IP Phone Feature Questions:

So I'm looking at the Data sheets for the 9900 series phones and wonder if you can answer a couple questions for me.

1) Looks like the phone can connect wirelessly instead of wired which is kind of cool, If you have the phone connected wirelessly, can you still use the PC port on the phone to connect a PC (i.e. use the phone to connect a PC that does not have a wireless NIC)?

2) Are there any limitations to the USB Headsets or should it work with "any" USB headset?

3) Am i correct in reading this is a SIP only phone and that it does not do SCCP Support?

4) Power is listed as 802.3af and 802.3at support.  Are there any limitations when using 802.3af instead of 802.3at? I am guessing the USB ports may require the Class 4 PoE?

5) It looks like these are just supported on Communications Manager 7.1(3) or later.  I assume they will work in SRST as well? if so what IOS version / SRST version would be required to support these phones (or does it matter?)
