You should ask Helge Deller for advise as he is the expert for Linux on PA-=
RISC
and also the upstream maintainer of the PA-RISC Linux kernel code.

Building your own installation media is a bit involved, here is an outdated=
 guide for it:

I'm not 100% sure what the best approach for building debian-installer with=
 your own
custom kernel is. But I guess you could just swap the kernel image in the i=
nstaller
images tarball with your own one and maybe unpack the debian-installer init=
rd.gz and
replace the modules directory in /lib/modules/.

What errors are you seeing? The vanilla kernel should build fine.

Here is a quick guide on how to cross-build a Linux kernel for SPARC, the s=
ame applies
to PA-RISC, just download the corresponding toolchain for hppa instead of s=
parc64:

No idea. Ask Helge ;-).
