I only have to wire up the freight station and engine house track, I have SPST switches for these, so I can store locos on them and still operate the layout. The soon to be laid staging track will be wired. I have also painted all of the track, up next is ground cover. I am really thinking about using Arizona Rock dirts and ballast in the yard, I have only used Woodland Scenics ballast, and it is a pain to work with when you glue it down.
I have also painted the tracks with Krylon camouflage brown, and I have drawn up the SPINS for Playa Desnuda. I plane to use these as a control panel and a diagram panel.
