First when I would go to turn the Xbox on the light was just a single red dot. I couldn't connect the controller, the tray wouldn't open, and nothing was being displayed on the screen. I unplugged everything and in the process noticed the power adapter light wasn't on so I switched out the cord that connects to the outlet with a new one and the adapter was working again, I turned the Xbox on again and this time the light went on green and I could open the disc tray, but the controller and display were still not working properly. The light would then switch back to red after a minute or so. I also tried using another HDMI and monitor to no avail.
Is there still something wrong with the adapter or is my Xbox toast?

One red light could mean an issue with your power supply, as you've already guessed, or a number of other issues, as noted here, in the trouble-shooting section for the Xbox 360. If any of the steps require a piece of hardware you don't have, you could try taking your console to a game store, preferably a smaller mom and pop type store, (they might be more accommodating) and asking them to plug it in for you.
