What causes the battery warning light to go out?
The light does not need resetting. It goes out instantly as soon as the fault is fixed. If the alternator is charging correctly, then it sounds as if the problem is with the wire that connects the alternator to the light (or that the alternator isn’t compatible, or has an internal fault which causes it to send the wrong diagnostic signal).
How can I tell if my Lexus suspension is good?
Usually a good visual inspection can tell you whether or not the struts and coils are good. On the struts, look for areas where dirt is sticking to them.

Your car should still be under factory warranty, so any repairs may cost you nothing. From my experience, a 2007 es 350 with a check engine light is mostly caused by a faulty air-fuel sensor or a loose gas cap. So, check if your gas cap is fully ratcheted, and drive for a day or two.

What should the voltage be on a Toyota alternator?
The battery provides the initial voltage and amperage to crank over the engine, afterwards the alternator takes over in generating the power needed to run the electrical systems in the vehicle. At idle under minimal load, a Toyota or Lexus’s voltage at the battery should hover at or above 14 volts (many times closer to 14.5).
