I have performed nearly every maintenance item on your list and it is not that expensive or difficult. Most of the stuff is "optional" meaning it is not impacting the ability to safely drive....except for your pedal-rod. These brakes are EASY (as others have stated) compared to other cars I have worked on. Slip on, slip off. They are also very cheap compared to normal jobs, the w123 non-vented rotors are only like 10-15 bucks a piece. Reman calipers and some $20 pads and you're all set. Hoses are fairly cheap too and might as well replace when you're in there. I did all 4 in a day and a half plus wheel bearings. Vacuum and electrical issues are solved with diligence, not money.

Just do all the work yourself and save the labor, and you will be fine.
