Perhaps, probably (never tried this myself). If your laptop can
boot from the cdrom, then it should work if booting from the same
pcmcia boot image works when using it from a floppy.
But in some ways this is silly -- the pcmcia image is designed for
installing from a network server, the idea is to boot from floppy
then install from the network once the pcmcia drivers are loaded.
Just use boot.img as your El Torito boot image and it will work.

No. The bootable redhat CDs simply use images/boot.img as the boot
image (set like that when using mkisofs).

man mkisofs will tell you how to do that.
(eg: ".. -b $bootimage -c $bootcat" ...)

It isn't difficult. Besides the man pages, there is a redhat cdrom
howto that can give you lots more clues.
It is possible to create all sorts of bootable CDROMs. tomsrtbt has
an ElTorito bootable cdrom image available (and a small shell script
that will recreate it for you after customisation). Pocketlinux,
smallinux, linux-router, smoothwall, vectorlinux and so on... most
of these work the same way when booted from floppy. The only
proviso is that the boot kernel MUST have cdrom support built into
it (and the bios is capable of booting from the cdrom).

What you want -- if you end up changing any of the packages in
RedHat/RPMS -- is genhdlist. You DO want to do that, because you
can put the updated packages directly into the installation. For
rh6.2, run genhdlist from the base directory of the cdrom image like
this:
genhdlist $(pwd)
That will update the RedHat/base/hdlist database file (which is used
by the installer).

USB isn't available with rh6.2 (not unless you use the rh7.0
2.2.16-22 kernel...)

You can do that already with the default boot.img setup -- IFF your
laptop can boot from cdrom. You only need to use the pcmcia boot
image when installing from an nfs network server.
