Don't forget to put ceiling outlets in for garage door openers. If your door is 10' tall set the outlet back from the door opening about 11' and about 16" off center so it doesn't interfere with the motor mount hardware.
Add a ceiling outlet right at your lift leg so you can hang a retractable extension cord...keeps cords off the floor. This is also a good place for a retractable air hose...don't forget to add mounting blocking between the trusses before you install the ceiling.
Only install 10 duplex outlets max per 20 amp circuit and you should be fine.
The 220v circuit needs to be sized per the welder name plate. If the welder is a future thing, install an empty 3/4" conduit from the panel to the location and pull the wire later. The 3/4 conduit will handle 30 or 50 amp circuits when the time comes...
