Setup Cubase for Live Use

Hi Everyone,
I have been recording at home for many years. I now want to play my music live. I play solo electric guitar. I don’t have a band. I believe the Arranger Track is the best tool for setting up a setlist. My question(s) is this:
For each song, should I do Audio Mixdown to that song (minus the guitar) to a Wave file and import that to my setlist project or is there a better way? (The setlist project will contain all the songs in the set.)

I also need some advice on the most efficient way to setup hardware on stage. All advice is welcome.
