As for the hex socket for removing the drain pan, I found myself in a similar situationj, too late and too grungy in the evening to go tool shopping. I took two 9/16" (wrench size - 3/8" bolt) nuts, jammed them together on a bolt and used that to remove the plug.
Make some sort of drain to help guide the oil onto the surface below the bike. Generally NOT the drain pan... : P The CD manual has a great diagram of an ideal drain piece, but it only sorta worked for me....
One quart of oil will do the trans and rear drive, but synthetic make the trans shift better, but is not necessarily recommended for all years of final drive. Decide for yourself.
Good luck. Plenty of folks here with more knowledge than me to help you out.
