Speaking of outdoor extension cords, what gauge do I need?

You can always use a Kill-a-watt device to measure current draw in case the manufacturer is off on estimates.

I also prefer green or black - just make sure it doesn't become a trip or mow over hazard...

You can get outdoor extension cords in those colors, but many places stock cords that can be sold to contractors. I believe OSHA standards call for bright colors to make them more easily seen, so orange, yellow, and similar colors tend to dominate.
