Hello. A rookie modder here. I intent to translate/edit Bioware's NPC names and (if possible) classes name. This image described what I'm looking for;

For example, I want to change Imoen's name into Alicia, and her Mage/Thief into Engineer; which script and files do I need to edit/translate? How complicated it'll be? I know it can be done, just that after looking so far I can't find any tutorials related to my questions.

Why would I want to do that? This is the motive.

Another questions while I'm at it:
1. What script I need to edit in order to change Aerie's post-transform portrait? Her .CRE files are ogre by default
2. Direction to tutorials etc about editing area's pop-up description would be handy
3. Additional guide on changing the race text description (Human) at low-left screenshot would also be handy

I guess that's it for the moment. I'll be studying more tools while waiting for replies. Thank you.
