Installing HDDOSD and BBNAV from scratch as well as other things...

okay, its me again, now with something else (if i should just have used my older thread, sorry for making a new one)
now, having a premade image to write to hdd is nice (as you dont need a modchip to install those) but when it comes to making custom installations you will run into problems.

before posting i already tried (and failed) in running the BBNAV 0.30 installer from the SUDC3 with ESR (i dont have a modchip, so running non-patched ISOs is not an option for me).
what i want to do/have is to create a hdd that boots into HDDOSD when started up and has the BBNAV 0.30 installed as app to run from OSD, as well as a noob-friendly tutorial in how to get the XMLs off the reiserFS partitions to translate BBNAV (i want to add a german translation, but the english translation by richi im using as base sounds weird in some places so i want to get the original japanese ones and try to use those as base) as well as "inject" my translation back in without overwriting the japanese original language files.
i know that there are various precompiled images out there, like the one vash posted in my old thread (which is the one im using right now), a couple of images included in the SUDC (the most interesting one is the 48bit HDDOSD, even though that would be only half as fun without a 48bit BBNAV...) as well as some premade images by krhacken that he posted on a russian site (but i cant access those, looks like you need a certain post count or special permissions to get to those images) but none of these images comes with the HDDOSD-BBNAV combo with BBNAV 0.30 (which apparently has a couple of features that got removed with 0.31 and 0.32), and i dont know how to create that kind of boot-combo (which would still be a problem if i was able to boot the utility discs, which i cant as my only boot methods right now are ESR discs and USB)

if im asking for too much (my coding/hacking skills are around 0, else i would try to do the hacking myself) or theres something on the web i havent found (i only checked the first 10 pages on google for this) just tell me,
still thanks in advance
