I have recently corrected 5 dialogues:

HROTHJ.DLG
DARJ.DLG
GOVAN2.DLG
IMOENJ.DLG
IMOEN2J.DLG

The patch installation file is here:

http://vlad.blackwyrmlair.net/files/NeJ2v43b.exe

Just install it into your main BG2 installation directory. It is aplicable for any saved game before leaving Irenicus dungeon in the second part of the mod. It also assumes you installed NeJ2 prior to installation of any other mod which modifies Imoen dialogues.

[EDIT] For those who wants to patch it manually here is the patch file:
