Dave, HDMI Female<->HDMI Female sounds good. I was looking for one, but coudn't find it anywhere. Where did you get yours? Any piece of cable that has a female Micro HDMI connector seems extremely hard to find.

This has the advantage of getting it clear of the dock area which is rather cramped. I was then able to plug a short Micro HDMI to HDMI male cable into that which are rather easier to find. Regarding the USB, then yes the newer Pi's can back-power through their standard USB ports. If you have an older Pi with polyfuses on the USB ports, then the easiest thing to do is the 'PiPass' mod which connects the +ve and Ground wires of the micro USB and normal USB together on the Pi itself.
