well, here's some things for you to think about

*) kernel patches come in two versions, one that you patch ontop of the
latest base release, or incrementals that patch between sub releases.  your
2.4.19-pre10 patch is most probably a patch that applies cleanly to a fresh
copy of the 2.4.19 source, and won't apply to 2.4.18-3.  
*) if your 2.4.18-3 source is for a redhat kernel, chances are it's already
patched in some weird ways meaning the patches you find on kernel.org won't
apply properly anyway.
*) there is a script in the /scripts subdirectory of the kernel source
called patch-kernel that takes most of the hard work out, i'd use that.

kernel.org shows the latest in 2.4 as being 2.4.20-pre8.

If you want this latest kernel, then get a copy of 2.4.19
(http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.19.tar.gz), the
latest stable release and extract it.  Then download the 2.4.20-pre8 patch
/patch-2.4.20-pre8.gz) and apply that using the patch-kernel utility.   now
when pre9 is released, you can download the incremental update and apply it
to your 2.4.20-pre8 source with the same utility, and continue updating like
this as development continues.

you might also want to consider using bitkeeper, but that is another
