Can I use the Thunderbolt Display as the only display without having to connect the magSafe to my Macbook Air?
The Thunderbolt Display it has two cables: one goes to the Thunderbolt port and the other one to the magSafe port. Once you connect both, you can close your Macbook Air display and instead of going to sleep the Thunderbolt Display turns on and you can keep using your Macbook with the fullest resolution. But you can't do that if you don't connect the magSafe port or if you disconnect the magSafe port when you are in this mode. The reason why I want to do that is because I read that is good for your battery life to charge the battery only when you run completely out of battery. I would like to know if there is any setting that I can change to run the magSafe as the only display without having to connect the magSafe. Thank you!

Don't worry about this at all. Keep that port plugged in. OSX has an ingenius feature that stops the laptop from drawing power once the battery is full. There is no need therefor to unplug your magsafe port.

I'd like to know the answer to this question as well. It seems strange to me that when you disconnect the magsafe, the display shuts off. It may be that the battery isn't sufficient to power the thunderbolt port with this kind of load on it. If so, then I would imagine that the answer to your question is "no." (But fingers crossed for a workaround!)

I don't think so.
"Apple does not recommend leaving your portable plugged in all the time."
I have this same problem with MBPro to TB Display. The folks at the Apple Store told me to run down the battery once in awhile (monthly?) to keep the battery healthy.
I have to do it off-line or sometime when I don't have the TB display in use. I can't run the battery down and have the TB display connected.
