Yes, you should just be able to do it in paint, just like the main screen, or you can use the "Last Key Press" window in HKN to get the mouse position.

I've never used VuhDo, but I would guess that you can import the settings just like any other addon. There should be a file in either

World of Warcraft\WTF\Account\ACCOUNT NAME\SavedVariables

or

World of Warcraft\WTF\Account\ACCOUNT NAME\SERVER\TOON

for Vuhdo.lua or something like that. Save your master's settings in a profile, copy that file to the same location in your slaves folder and you should then be able to load that profile for them.
