Default Coil over springs, asking for options explained

My mechanic is installing a Moser rear end this week. He will tell me the maximum 17 inch wheel/tire combo will work beneath the rear wheel wells and suggest the best 17 inch wheel/tire for the front. At that point, I’ll buy the reproduction Rally 2’s and hopefully redline tires. Coker has redlines, a maximum of 235’s. Any experience and/or suggestions on wheels/tires?

My mechanic will also install coil over springs. He suggested QA1. I don’t know one company from another. I see options of Single Adjustable, Double Adjustable, and MOD Series. Then the next set of options are Spring rate: 130, 150, and 175. Can anyone explain what these options are?
