Assuming one is going to install a new(vanilla) kernel, does SuSE keep packages, a patch, or source anywhere so that we could apply it to a new kernel?

Or at least a list of what they do to it so I know what I would be losing or missing out on should I go with a Fresh Kernel?

You can download and extract the kernel's src.rpm (not the source.rpm!). This will contain all patches applied to the vanilla kernel.

Sorry to play the NOOB card, but this whole process of kernel recompile is fresh to me.

"You can download and extract the kernel's src.rpm"
I assume you mean from a SuSE FTP site, right?
Then as for extracting, what do you mean? I can extract just the patches out of there?
And are all the patches from SuSE's 2.6.13-15 applicable once I have extracted them/it to the new 2.6.14 kernel(fresh from Kernel.org)?

Sorry if this was confusing:

src.rpm can be downloaded from the SUSE FTP server. In case of 10.0, you may need to download the DVD-SRC-GM ISO, since I don't know if the FTP installable version already exists.

You can't install src.rpm with YaST, but with rpm -i *.src.rpm. It will be copied to /usr/src/packages/. In the subfolder SOURCES you should find all patches and the kernel source. It's a bit tricky to extract single files from the rpm, but possible. You can use rpm2cpio and cpio:

EDIT Forgot your last question:
I am not sure if you can apply all those patches to the new vanilla kernel. Some may have already been merged with the new kernel anyway (SUSE is quite active in kernel development). This is tricky!
