Jason,
This is a bit of a wild stab at the problem but here goes.
First, classic symptom of alternator starting to misbehave is the warning triangle intermittantly showing up. It is sometimes assocoated with the warning chime. In fact you may have observed that when you let off the gas the flickering increases; start to accelerate and the warning may stop. Solid red means a solid fault is detected.
The alternator has some circuitry that regulates the voltage out. If some of the components fail you can get an overvoltage and dirty voltage (AC current). The rising gas tank would suggest overvoltage.
Get a volt meter and check the voltage at the battery before running then while running. My guess is that you'll be seeing very high voltage swings from below 12v to above 16v if you're alternator is not regulating voltage properly.
Good luck,
Michael B.
