Awesome Astro - I am excited for you and can't wait to see how it goes!
A few suggestions I can think of:
Creature comforts:
Toilet, shower, microwave, refrigerator, TV, clothes washer/dryer and maybe even a dish washer with a small kitchen area and kitchen cabinets.
Shop:
1. Air drops in handy places with reel hoses
2. Plenty of electrical outlets and some in the ceiling to drop down for the car lifts
3. Concrete floor 12 inches thick, reinforced or whatever is recommended for heavy loads in your area
4. TV
5. Insulate walls and roof
6. shop sink for washing up
7. plenty of LED lights - saves power and are brighter
8. garage door opener
You probably already have, but draw out your floor plan and then get the dimensions of all the stuff you want to put in there and place them on the floor plan to check for work flow and other space saving ideas. (where to put the lifts, air compressor location, etc.)
BTW: Girly posters recommended, but wherever you put them the wife will notice right away.
