I used that one and the afformentioned influence FAQ; the latter helps you know which people to use, and when. But I didnt play Dark Side yet.
I was able to everyone to jedi who was able to get there, get all the story dialogue from Kreia available, and get to Light Side Mastery. I also made sure my character had the INT (and Computer and Repair skills) to get all of T3-M4's info as well.
I wasnt able to get any of HK-47's info, BUT I did manage to get enough influence with G0-T0 to find out some really interesting things (which isnt in the FAQs...). If I had gotten HK-47 earlier, perhaps I could have managed to build influence with him and recover the light side points, but I got him really late in the game.
In another thread (in the Console Games forum) I posted my Workbench FAQ
. Unfortunately it was rejected by GameFAQs, but it is more complete than the one they have there (it was rejected because there is already a Workbench FAQ). So hopefully people here can get some use out of it.
