Boo! Do you live in 20th century? It's a crime to not use git, especially
when patches are involved. Even if they're not, you save time unpacking /
downloading updates / switching to other releases.

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git

This won't let you uninstall cleanly, or deploy to other machines.

make-kpkg --rootcmd fakeroot --initrd -j6 linux-image
(no --initrd if you don't want initrd, replace 6 with the number of cores in
your box)
dpkg -i ~you/linux-image-*.deb

make-kpkg will handle grub/lilo config automatically.

The first time you need to copy it by hand as .config to your linux source
directory -- if you want to start with the distribution kernel, that has
every obscure driver as module. You can trim that to only those present
on the compilation box with "make localmodconfig". Another target of note
is "localyesconfig" which converts modules to built-ins, something you want
in a non-initrd kernel.
