MOOG LIBERATION restoration & questions?

Hello,
I have just buy today an MOOG Liberation and I have for a start a few questions.

  1. The synth is in good shape but the black cabinet need to be restored (sanded and painted). ¿Any advice ? ¿Its all the cabinet in wood?
  2. I have other MOOG analog synths (Minimoog, Multimoog and DVCO ). ¿ Can I connect one these synths to the liberation Rack and control the minimoog for example from the liberation keyboard ? ¿ The same with the DVCO ? (it will be wonderfull to get 2 more oscillators form the Moog DVCO rack in the Liberation = 4 oscillators!!!).
    Thank you in advance.
