There's also the Era Report 3145(I forgot there was an Era Report 3145 and looked for the info in FM3145 instead) which would probably be more helpful. I don't really know any online sources that would spell it out, but for the most part, it isn't really that complicated. Just don't pick factions that are dead, and some minor changes to some factions...
You could also jump back to FM 3085 which will provide for post-Jihad characters that might help.
