CDCheck can do a bit-by-bit comparison, not just a CRC32 check.
so if you compare 2 data CDs with the Compare process in CDCheck and the result is OK no errors, that means the the discs are bitwise identical (at the OS level, not at lower levels on the CD such as EFM or whatnot).
this is what i do and i find it good enough.

yes it will, it's still a data CD.
once again, you should do a Compare process, not a Check (CRC verification) process.
Yes, for us (paranoic people) Nero should check image file against the original CD, then check the burned CD against image file, and at last check the burned CD against the original CD.
you can do this, but if it's a Nero image you have to mount it first (Nero DriveImage?), but i don't see the point of comparing the source or result disc with the Nero Image.
just compare with CDCheck the original CD against the copied CD.
