I know we are a ways from putting the boxters in hibernation, but this will be my first winter. If i put a battery tender on the battery, should you take the cables off the battery or just leave them on and turn the key off?

Most people leave it connected. The cigarette lighter tenders require it, obviously. It uses less energy to disconnect it.
I've used the CTEK battery maintainer for the past three winters and it's worked great. I don't disconnect the battery and I use the cigarette lighter adapter. Makes for quick getaways when a nice day comes by. I bought the CTEK with "Porsche" on the front so I paid too much.
