"man e2fsck.conf". Short version; place in /etc/e2fsck.conf:
[options]
allow_cancelation = true
At this point, it is up to whatever system (sysvinit, upstart),
etc. to allow a ^C to be passed to the fsck process, but as long as it
receives a SIGINT signal, it will do the right thing.

You can't really do the 'info gathering' thing with the hopes of
speeding up a read/write check, but what you *can* do is check for
errors, and if the filesystem is clean, reset the last fsck and number
of mounts since last fsck count. This requires that the filesystem be
located on an LVM volume, however. The shell script to do this is
attached. It is suitable for running out of a cron job, or from a
desktop session while the user is logged in.
This also answers your wishlist from sysvinit:
