as long as the ripping is not missing "pregap" (especially track 1
index 0), which has to be set up a certain way in EAC, then yes.
you should try an experiment with one disc first.

FLAC uses the same tag standard as vorbis.  ogg has no tag standard.
the vorbis standard does not mandate any tags, but has some
recommendations.  I think the current convention by users is to
store lyrics in the LYRICS tag.  cover art is not part of the tags,
it will go in the PICTURE metadata block in upcoming FLAC 1.1.3:
