Del's approach is a great way to get started. It will at least give you some tracks for the gigs

I used my Ipad or Iphone to play tracks for performance. Either cable direct from the device or use bluetooth.
I use a piece if IOS code called Anytune Pro to manage songs and setlists for performance.

One tool I have found very helpful in producing a consistent non-clipping output levels for my backing tracks is a piece of code called MP3 Gain. This keeps you from having one track too loud and the other too low in volume. It also identifies clipping when your mix is too hot. Fix clipping in the mix not at mp3gain.
A LUFS meter and Limiter is important. I personally like to EQ each track in my DAW. I use automation to accent different accompaniment parts to make the track more interesting.

None of it is hard. Truth be told I learned a great deal here on the BIAB forums. There are some folks with skills here.

If you want to sound good out in public, you need good quality tracks.
It is work.
