There are probably a few seconds of silence at the end of each cut,
which you might consider shopping.

First off, do remember that a CD plays from the inside out, so the
problematic tracks would probably be at the end of the album.

You can shorten them via resampling by a few percent while leaving the
pitch as is -- Audition, for example, will let you do that. Thing is, it
works best on 32-bit floating-point files, so for best results you'd
need to shrink the files before they're dithere down to 16 bit.

I'd guess throughout; the way manufacturers get 80 minutes onto a disc
is by departing from the usual intertrack* spacing. (*Yes, I know it's
not really "intertrack", just as a 78 doesn't normally have "grooves" --
just one groove per side. Whatever -- they make the disc with a
non-standard spacing, so some players will gag all the way through as
their servos fail to keep the laser properly focused. But I think
players that won't play an 80-minute disc are pretty thin on the ground
by now; correct me if I'm wrong.
