This forum has lots of good information for all of the topics you mention, so you may want to read those first. To avoid repetition, please then post any detailed additional questions that you may have and which were not discussed before.
Regarding car insurance: As all German cities are VERY manoeverable (at reasonable cost) by public transport, I recommend focussing on the other aspects of your move first and getting a car after those are settled - if you still feel you need onw (many people here don't!). You may then also look ionto car sharing schemes, which are easier and cheaper for occasional users.

I have asthma and I need A/C--is that going to be a issue?

If by A/C you mean airconditioning: That isn't very common in (temperate climate) Germany - except in big, modern office building (where it might run during the hottest few weeks in summer).
Airconditioned residential buildings are nearly non-existent.

Since your profile indicates that you are above 55 years old, a word of caution:
Joining the public health insurance scheme is near impossible at that age, so you must go for the private scheme, which will NOT be cheap, especially with a pre-existing condition (asthma).
Read existing threads about it and get independent advice once you arrive in Germany!
