libc is libc.so.5 (well if it's up to date that is ;), binaries compiled
against it are closly coupled to the kernel. glibc is libc.so.6, it's
GNU's libc, and it's much less closly coupled to the kernel (ie you're not
supposed to include kernel headers, as in anything really in
linux/include/*, you're supposed to have a local copy of the header if you
really need it (eg mount should have a local copy of <linux/mount.h>)).

Yes, libc is libc major version 5, glibc is libc major version 6.

Either, both. There's not really a restriction. You may consider
installing a distribution that uses glibc, which would be Red Hat 5.0, or
Debian (I'm not 100% sure, but I think it does;).
