Adding functionality to my Mopar/Jeep shop

Had a retired electrician come over today and put a couple 220 circuits into my pole barn. I have 200A service and only maybe 4 15A 120V circuits on it now. This runs the outlets in the walls, a lighting circuit (with one plug) to the unheated storage side of the pole barn. I have a 30X48 pole barn split in half with heat to one side. The heated side (insulated) has a natural gas furnace about 4 or 5 outlets and multiple outlets in the ceiling for lighting. I had him run one 20 amp 220 for a compressor and a 30 amp 220 for a welder to the unheated side. I wanted the noise and welder to be outside of the area that I want basically clean and quiet so I can build another motor/trans in there in the future.

My question is now what compressor and welder should I look for in the next few months. I plan to pipe compressed air around the shop to run air tools mainly and possibly a DA sander on the unheated side (dirty side) from time to time. I want a good hobby MIG and potentially a basic plasma cutter also in the future. My box has tons of capacity left and the electrician is always available so I can add more circuits if necessary.

Next question relates to lighting. I have a dozen 120 plugs or so on two 15 amp circuits already distributed around the ceiling. I bought some cheap florecent lights last winter and it seems a few of them didn't like the cold. I am ready to buy some longer term lights now. Anybody have some suggestions for a shop that might vary in temp due to me being in Michigan.

Lots of questions I know. I am not an electrician and not rich but I am trying to build a great working shop. Any advice would be appreciated. Lift will be next year with a 10 foot ceiling when I save up some more dollars but I will save those questions for later.
