Studio 1 makes some good zoom controllers. You can check them out at
http://www.studio1productions.com/zoom-controller-menu.htm
I use the ProZoom 2 ($199.95)
It allows you to zoom, focus, turn the camera on and off, start and stop recording, switch between auto and manual focus, as well as turn the screen display on and off.
They make one that is a little less expensive, but it has less features.
Also, check out the Manfroto 501 fluid head and legs...great set up, runs about $270
