Everything was set up for me a Nomad harness and LP105s with stage rigging. I used rental gear from the LDS for the course, as I was still unsure what to buy. It ticked off all the PADI standards in terms of skills and drills, as far as I can tell.
The sidemount course was short - an hour in the classroom, maybe an hour and a half in the pool, and three twenty-something minutes dives in the local quarry, in the 50-70ft.
I'm happy to answer the question from my personal perspective, the particular instruction I got, my perhaps somewhat differing diving goals, and what I think could have saved me some time and frustration down the road.
