Go ahead and replace what's there. I trust you guys enough to believe you won't lead me wrong. Besides, if it is off somehow I can always change it later.
Xhai, I'm not having any issues with the CPK at all. If you wanted to help with the translation you could. Alternatively if Maxtram needs any help with the images you could help him out.
EDIT: Pics of Maxtram's Menu Patch.

OH! Forgot, the last item under the "Maintain ALL the LBX" section is Repair Kit. That one can be a bit tricky.
