Thanks to everyone for all your help & comments.
PottsBr - I was also trying to decide whether Centauri names given in the show were first or house names. I came to the conslusion that any name spoken with a title, e.g. Lord Refa, was a house name. Not sure about the women though since Lady Morella was the wife of Emperor Turhan

Argh, it gets very confusing!
Elfman - thanks for the info on Drazi names. My name creator is basically a database of first/last names but for the Drazi I will most likely program your rules in (if that's ok with you of course?).
That Minbari dictionary is also very good.
I have just ordered the race books so hopefully they will help a bit too
