Yes.

Yes.  You don't have to be root at all except for the installation.  All git
tasks, and the build (via make) itself *should* be performed by normal user.

No, kernel-source package is totally irrelevant here.  We just need
kernel-desktop or whatever kernel-binary package with the corresponding kernel
version.
Boot with 3.8 kernel.  Then run "make localmodconfig".  This is an important
step.  The later step, the build and install, can be done on any kernel,
though.

Then something wrong in your git repo.  You must use Linus' git tree, not
SUSE's one.
