Did you already do the SMC reset? If not do it even twice or thrice (firmware can be suprisingly stubborn). http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US

It sounds very much like the battery has died. What does the battery meter say in the menu bar, if you click it? Usually if the battery has already breathed its last, it will say "service battery" or even "replace battery immediately".

Your SMC reset did not work. Check your SMC reset procedure. You have a 5 Years old battery!- it is EOL, get a new one.

Apparently 3rd time is the charm. I asked to have this replacement power supply replaced one more time, and the 3rd power supply works fine. Very odd, but things are operating fine now.

It's perfectly safe to use the MacBook Pro Charger with a MacBook Air. Going the other way around though will most likely charge the MBP at a slow pace, like an iPad charging through USB or a 5W Wall Adapter. For more information, see this Apple KB article: http://support.apple.com/kb/HT2346

You can set up a hot corner to turn the display off without going to sleep. Go to System Preferences → Mission Control → Hot Corners and set one of the corners to Put Display To Sleep. Wake the display by pressing any key.
