However whenever I try to run something as an administrator, or whenever windows decides it wants an administrator to approve something, I lose all mouse and keyboard interaction until that whole task is completed. I can see what is happening, but not do anything. Interestingly, if directly on the computer I take the mouse-focus from the program that is running at elevated privilege I can then regain control in VNC, but just not touch that privileged program.

This behavior is normal. Beginning wit Vista the new method of ganting privileges was introduced for actions that require system files modifications. This metod works by running the privileged processes separately with administrator privleges. Now the trick is that the graphical representation is privilege separated too. So in effect you have a composited image comprised of 2 layers, one user and one administrator (i think its provided by the system user, that has even higher security clearance). Normal user level processes cannot interact with them.
If the VNC server (ANY vnc server, not just tightvnc) runs in service mode, you can interact with those windows with no issues. I use it frequently and it works.
