I think you need a 'mkswap partition_name' first, but
this may have already been done if you don't repartition.

I always like to use -avH and --one-file-system options in addition to
-essh.  -a sets most of the other options needed for backup (recurse
and keep all attributes possible) with the exception of hard links
(thus the -H).  The -one-file-system keeps it from wandering into
/proc or a mounted cdrom or nfs mount and you need it to skip /home
if it is on a different partition that you want to do separately.
Also, rsync will create one (and only one) top level directory for
the target but I always forget whether your syntax would make a
/boot/boot and put everything under it or not, so I like to cd
to the top of the source directory and use '.' as the source for
rsync to ensure that it won't make a new directory to match at
the destination.

If you had done that before the other steps you would have ended
up with a grub loader installed. Even if you screw up the grub
config later, you'd get an interactive grub prompt where you could
type in the location of the kernel to boot.
