Hi,
obviously you tried to patch a vendor supplied kernel (RedHat kernel) which is
always a bad idea because these kernels are always patched with a variety of
things which makes it very difficult to apply patches that were intendent to
be used with stock kernels. Then you tried to apply a newer patch to a kernel
which was already patched with an older version of that patch. That will never
work...
The most recent ext3 patch is against kernel version 2.2.19 (ok, I know, that 
is not exactly true but works...).
Here is how to do it:
get a fresh kernel tarball from ftp.kernel.org and untar it in /usr/src:
cd /usr/src
rm -rf linux
wget ftp.kernel.org:/pub/linux/kernel/v2.2/linux-2.2.19.tar.bz2
tar xIvf linux-2.2.19.tar.bz2

Now, get the ext3-0.0.6 patch, untar it and apply it:
wget ftp://ftp.*.kernel.org/pub/linux/kernel/people/sct/ext3/ext3-0.0.6b.tar.bz2
tar -xIvf ext3-0.0.6b.tar.bz2
cd linux
cat ../ext3-0.0.6b/linux-2.2.19pre14.kdb.diff | patch -sp1
cat ../ext3-0.0.6b/linux-2.2.19pre14.ext3.diff | patch -sp1

>From here on it is just normal stuff: make menuconfig; make dep clean bzImage
and so on.

And, as usual, my little hint towards the little FAQ that I wrote ;-)

Good luck,
