Disabled guy needs mod help

[Gimpygod]

I am a disabled guy (rare form of muscular dystrophy so I have sensation throughout my body but effectively quadriplegic due to lack of musculature) who just found world of war craft on March 10, 2009... my life is changed forever. I've never been able to walk or even scratch my nose yet inside this world I can go anywhere and actually explore. I have loads of fun just walking and looking around, fishing, cooking; the minutia is entertaining to me. (if you want to check that I'm not just pulling your leg I was part of the "everyone has a story" series on the today show in October and featured again in December)

The way I have to play is rather unique in that I have a mouse which controls cursor movement via a camera monitoring my head movement. Meaning if I turn my head to the left the cursor moves left at the corresponding speed. I can only access left and right mouse click buttons which are placed under my thumbs -- left click left hand, right-click right-hand. While I can do many things with this arrangement some fundamentals are currently out of my reach and I wonder if anyone here would know of an add-on which could help or might consider developing some of my ideas so others with disabilities could more easily partake of the joy. Heck, some of my ideas would actually improve the game for many. Stuff I need:

1.) Probably the easiest but unavailable within the game would be the ability to move the shift key somewhere I can get at it. I call this the "looky" button because I tell my nephew, "hey, hold the looky button so I can see what this is worth at auction." I could move the jump button over to the numerical keypad so I can access it by poking with a stick in my mouth. (an altogether different problem because when I move my head to jump the cursor moves making me run in a different direction... drag). Forgot to mention that I have the keyboard in front of me but turned 90° so I can access the numbers and other keys clustered right there with a mouth stick. If I could move shift-key over to the*or - I can do a lot more by myself or at least not have to scroll through 20 pages to see what bronze bars are currently valued at.

2.) Chatting with people would be awesome! Currently I have an action bar full of macros so I can relate to people that I'm unable to type but can do voice if we are in a party. If there was a pop up keyboard that allowed me to type by clicking with the mouse that would be awesome... if it looked somewhat medieval that would be nice so the overall ambience wasn't ruined.

3.) Currently I am only able to run straight forward and turn by holding both the left and right click in simultaneously and jumping is unbelievably difficult, takes a lot of time and only useful to get over stationary objects. Meaning I am being completely crushed at battlegrounds and other player versus player material. Here are some of my ideas to increase mobility:

Right now I'm holding the left click to look around and then press right simultaneously to begin moving. Would it be possible to hold right click and then press left to move backwards? If that doesn't make any sense please say so and I will try to be more specific.

If there was a little circle at the bottom right hand side of the screen that worked as a proportional joystick that would be unbelievably awesome. If you could just left click in the circle and hold then move the cursor around for up, backward, left, and right that would be unbelievably cool. In this scenario the right-click could be then used to jump. Again, I'm not sure how much sense this makes that I could clarify if necessary.

I have more ideas but this first message has gotten ponderous so I will cut it short and say thank you for reading, hope someone can help and most of all enjoy your World of War Craft adventures.
