What's happens if you rip without ReplayGain

[Marshall]

In the instructions, we're told that we should set DSP effect to "ReplayGain." But I noticed the following warning on some of my discs when I did that:

Warning: Normalisation gain would have resulted in clipping, gain has been reduced to prevent this:
Loudness=-22.77LUFS, Gain=4.77dB, Maximum True Peak=-1.00LUFS, True Peak=-3.14LUFS, New gain=2.14dB [clDSP::EndConversion]

I didn't know what this meant, but it didn't sound good, and anyway I don't really see the point of ensuring that "tracks from different discs all appear with the same volume" - I don't necessarily listen to chamber music at the same volume as rock. So I unclicked it.

But now I'm wondering that perhaps I just don't understand the function of this setting. So here are my questions:

1) Is this setting necessary?
2) What happens to the music if I don't click on this?
3) If I don't click it (which is the situation I'm in) and then later decide that I should've clicked it, do I have to go back and re-rip all my CDs, or is there another way to manage this?
4) If I do click it, which is better: track gain or album gain? The default is track gain, but I would think that a track within an album that's supposed to be quieter than the others should remain so, and therefore think Album Gain is better.

Thanks for your help.

To my understanding:

1) No
2) Nothing
3) No need for re-ripping, but just batch converting

When ripping CDs, there's no harm in creating the ReplayGain tags using The ReplayGain DSP (not the ReplayGain (Apply) DSP). You can save both track gain and album gain tags.

I use the following settings when ripping CDs to FLAC:
