:1. Are CDs recorded in 48 kHz/20 bit/24 bit or 96 kHz and, if so, does the A110 convert their digital audio output to 48 kHz?

No CD's are 16bit 44.1 kHz.

:2. How can I tell when a DVD (or CD) is recorded at 48 kHz/20 bit/24 bit or 98 kHz? That is, how will I know when to use the regular audio output instead of the digital audio output?

If your receiver has a "status" display then you should be able to tell what sampling rate the DVD audio is.

:3. Since the regular audio output (not the digital audio output) of the A110 does not convert signals to 48 kHz, what would be the disadvantage of simply using the regular audio output all the time?

The disadvantage is that if your receiver/processor does all it's processing, volume control etc in the digital domain, by connecting using analogue outputs from your DVD player, your receiver will have to convert the output back into digital and then back into analogue before it can be sent to your speakers, thus destroying both any benefit of the 20 or 24/ 48 or 96 audio, and any 5.1 channel output (the analogue outputs send out a downmixed DPL signal)

The only circumstances in which an analogue hook up is beneficial is if the whole of the signal chain downstream of the DVD player to the speakers is 100% analogue and it is 2 channel material to start with.
