A couple of questions, first, is the small room off toward the corner a half bath? What are your lighting plans? How do you plan on finishing the floor?
This is my personal preference as far as finishes and colors in a shop. I like white for ceiling and walls (at least the upper section) and light gray for the floors (optional on lower part of walls). This helps maximize the efficacy of your lighting whatever you select since those colors will have pretty good reflectivity. For the floor finish, I like a smooth epoxy finish with a polyurethane topcoat.
I have a mini-split AC/heat pump combo and while it works well, there is no way that you can expect it to cool or heat the shop area if you leave the bay door open. You open the door to move stuff in or out and then you close it. You might also consider some ceiling fans. I did that as a bit of a last minute afterthought and am now glad I have them. Just make sure they are mounted below your lighting to eliminate any "strobing" effect but above any of the garage door related stuff and out of the way of the lift and whatever you want to put on that lift.
For your garage door, You want the guides to be way up at the ceiling. Otherwise you will not be able to fully use the lift with the door open or even to open the door without lowering the car enough for the door to clear. If you elect to go with an electric garage door opener, I would suggest that you consider one of the direct drive, wall mount unit such as this to get the lift mechanism out of the way:

Lighting has changed significantly since I built my shop and while it still works well, I would take a different and newer equipment path these days.
Attached is a shot of my shop interior as it was being finished up. You can see in the foreground a more conventional garage door mechanism that is for the bay to the left of the two post lift. The lighting and color scheme can also be seen in the picture. The red, well, my TR6 is signal red.
