Todd, welcome to the insanity!
I don't have wisdom to offer about three of your four questions. For #2, do you have automatic climate control, or manual? If it's automatic, which one is it: a row of vertical buttons, or a row of horizontal buttons? if it's a row of vertical buttons, that's the ACC system, used on 1978-1981 US-spec 107s. If it's a row of horizontal buttons, that's the ACC-II system, used on 1982-1985 US-spec 107s.
The bad news is that the ACC system is known to have problems, and in particular uses a servo made of unobtainium.
Also, it's properly referred to as a 500SL. The swap of the class letters to the front didn't happen till the 1994 model year, after the 107 ended production.
Finally, it's a good idea to fill in your profile and mention not only what car you have, but also where you are.
"Engineered like no other car in the world." That's both a bug and a feature.
