You can skip 2 and 3.  Installing a kernel .deb will automatically put
the new kernel into flash.

You mean flash memory, not boot loader.  In any case, your slug is
configured in a way that a newly installed kernel (assuming you
install a .deb and not a kernel by hand) will automatically write the
kernel to flash.  You don't need to do anything - only reboot after
the upgrade is done.

You don't need gcc if you merely want to install a kernel .deb package
from the archive.  You only need gcc if you want to compile your own
kernel, but there's no reason to do this.  Installing a new kernel
will automatically replace the current kernel with the new one in
