Ok guys. More roadblocks for me.

Question 1: How do I tell which Rev I have of Raspberry Pi?

Question 2: Which one of theses wires (if any) are my common wires on my solenoid valve?

Question 3: Everytime I download this gdata python client package it wont unarchive. Arg!

I have limited time to get this dang thing operational today while I have an HDMI cable, mouse, and keyboard on loan from the school. Please please please help me out. I’ve tried to wget, I’ve tried to apt-get install, I’m lost.
