A couple if ideas you might consider.
An option to get your controls off the desk is to attach the HOTAS to your chair. You can either buy platforms for this or make your own. Ofcourse that depends on the chair. This was my solution which I am quite happy with. I also mounted a mouse pad on the chair. (wireless Razor Mamba).
I dont know if you are thinking Track IR but if you do, go with the Pro which you can easily convert to wireless. This works well with a wireless headset. Who wants wires hanging from their head anyway? If you search a little there are some threads on how to do this. Some better than others so choose wisely. It is important to get the right battery. I have been using the same one for over 5 years now and it has never died during flight time.
Have fun building out your system and rig!
