There's another explanation for the "she's rich" versus "she's beautiful" line(s). The first time Luke sees Leia (on the hologram), he says "she's beautiful". Later when he's describing her to Han, he says "She's...." and instantly the mind fills in "beautiful". But since he's talking to Han, he doesn't say "beautiful", he says "rich" - which is rather funny actually. The mind then "remembers" what it was expecting... I know I was slightly (even possibly subconsiously) surprised every time I heard "rich". The existance of an earlier extended dialogue may just be coincidence, providing confirmation of the memory. Watching the script reading tests in "Deleted Magic" (many of which I think I saw before, ages ago), there obviously was a LOT of lengthy lethargic dialogue that thankfully got tightened up.
