> -how to make the wood panels look great.

I've had great luck with lemon oil and orange oil; go with orange oil
since it doesn't contain mineral spirits.

> -how to make the metal panels look great.

This one is easy: a damp flannel or terry cloth will do with a little
windex or simple green for tough stains.

> -touch up paint for scratches on metal?

use fine grit sandpaper to feather the edges before painting.

> -rust removal?

If it's on screws or hardware, get new screws or hardware.  If it's on
the metal panels, sanding is your option.

> -tolex cleaning / polishing?

armor all products are great on tolex; so is simple green.
I also use simple green for cleaning cables that are sticky from beer
and sodas.
