comment Toyota Celica battery light on but alternator appears okay on visual/auditory inspection
Where are you getting your figure of 13.8v as the maximum charging-state voltage? It depends on the car, but that's near the minimum of what any functioning alternator should read -- at least a volt above the battery's nominal 12.6. My car's alternator is specified by the manufacturer to run in the 14.1 - 14.8 range, depending on temperature. Going over 13.8v while charging does not necessarily indicate a problem.

Other things besides emission problems will turn on the CEL; without knowing what the code actually was, it's impossible to say why it turned on or off. (Also, it wasn't your timing belt that was replaced, as Paulster noted on your other question.)

comment Vibrating sound and shaking when turning the wheel after changing timing belt?
There are two "accessory" belts on this car; if the arrows are pointing to the rear one in the picture, then the belt was for the A/C compressor, not the power steering pump, which is to the (car's) right of the alternator (just visible in the top left of this picture). The front belt drives the P/S and the alternator, and has no separate tensioner; the tension is adjusted via a bolt on the alternator. It's possible (even sensible) that both belts were replaced at the same time, but if tensioner was involved, that was the A/C belt's. @KingsInnerSoul

Also, if the cat failed within a year, something else is with your engine. I've heard people implicating failing head gaskets for that.

That's definitely the right ballpark. Catalytic converters are expensive. I'd think you could get a cheaper sensor, but I'm not positive.

The diagnostic code will indicate which it is. You should be able to get it read for free at your local parts store. There should be, as far as I know, three sections to your exhaust: first section includes the front cat and sensor, second section the rear pair, and the last goes back to the muffler. Unless somebody did something weird: my Forester had a piece of pipe welded across what should have been the joint for the two rear sections when I got it, so when I needed to do the rear cat, I had to do the end pipe as well.

Note that there's two cats and two sensors; you should double-check which are problematic.

comment Are there any double-DIN bluetooth stereo system that can connect to multiple devices at once?
The problem is that the result of "Are there any Xs that do Y?" and "Which X should I buy?" is the same: a speedily-obsolete list that's also a potential spam magnet. I don't think there's a good way to ask this on a Stack Exchange site.
