Could be your first project could be to build a sound dampening enclosure for your compressor. Here't the time tested (at least by me anyway!) design use when I have to be more quiet on certain jobs.
Make a box out of a sheet of plywood (if you can't cut it, the lumberyard will) that will hold your compressor PLUS some insulation. I make a box, then use whatever I have on hand (usually caulk) for adhesive and glue a couple of layers of foam board on the inside. Make sure you plan your inside dimensions to allow for about 3 - 4" all the way around the compressor minding where you put the compressor inside. The compressor heads will get quite hot if you run it a lot.
I put the door on the front, and hinge the door with some cheap door hinges. BTW, the door is insulated, too. Leave a generous slit in the door so that you can get the power cord and air hose out of the box; keep in mind this will be a vent for the compressor as well. I wouldn't worry too much about heat since you are probably not going to be using this in a manner that will cause it to run a lot. However, you should check it inside after running the compressor for a while to make sure it is no more than a little warm inside the enclosure. If it gets hot, take a break and leave the door open for a while.
On mine, I put a small 2x4 frame on the bottom so I can put some cheap castors on it so I can roll it around.
You will be astonished how quiet this setup will be. Also, the box makes a dandy enclosure to hold your hoses, nail gun and nails if you can keep it in a secure place.
