wireless switch closing? JamMan looper


I want to a use micro-controller together with a wireless receiver to close the 4 foot switches and a few small surface mounted buttons on a JamMan stereo looper, I have a few questions about the components needed:

The jamman casing is made from metal and I want to install the receiving sensor inside, I'm not sure what kind of wireless sensors I should use, IR sensors, 2.4ghz, or something else?

Would I need to use transistors, relays, optos,etc... or could I just use the digital pins on an atmega IC to close the switches, i.e. connecting the pins directly to the switches.

thanks for any suggestions

For beginning, I strongly recommend using these RF link antennas.
