Don't see the point in cutting the second trace though. You could just use the original ground point the original LED used if I'm not mistaken. Correct me if I'm wrong...

I pretty much understand that the positive lead has to connect to the 3.3V header on the power board. What I don't get is the grounding part for the negative lead. You said that I can use the same ground the previous LED uses but I'm not exactly sure where it was grounded in the first place. I've never modded anything in my life and this is basically going to be my first project.
To say it in more technical terms, you need to apply positive voltage to the anode (long leg) and ground the cathode (short leg). So the original LED on the board already has a ground point. That's how LEDs work. Positive voltage goes in on one side, and out to the ground...
Remove the original LED. Cut the trace on the controller board that connected to the anode leg of the original LED. Connect the anode of the new LED you want to use to the 3.3V point on the powerboard. Connect the cathode of the new LED you want to use to the same point the cathode of the original LED was connected to. Hence why I said you shouldn't cut both traces that lead to the original LED. One of the traces (the ground) can be reused. Only the voltage point has to be replaced with a 3.3V point...

Ok, so I'm not completely sure what a "trace" is. In this case the traces are under the LED right? I assume that its the two silver points right under the LED. So If I desolder one point won't I need to de solder the other point in order to remove the original LED?

A trace is the little line that goes from one point to another on the board. You can solder to a trace to create a jumper but I would never purposely break a trace. If the new led has the same number of legs as the old one then just put it in as the difference in current drawn will be minimal
