Well, this has finally been cleared up (unless he changes his mind yet again).
Thanks for the quote InsaneSith for the original source (I missed that post before I pasted this in). ;)

Sorry if this has already been posted, but there were some interesting quotes in there:
IGN Film Force Interview with George Lucas (
http://filmforce.ign.com/starwars/articles/613/613366p1.html)
On the nature of Stormtroopers:
"The idea is that over time, there were new clone strains introduced, and then they even conscripted guys to be Storm Troopers. So it's not just purely clones: It started out as clones, but then it got diluted over the years as they found out they could shanghai guys [more cheaply] than they could build clones."
About Han & Leia:
"Han and Leia probably did get married. They settled down. She became a senator, and they got a nice little house with a white picket fence. Han Solo is out there cooking burgers on the grill."
On the Honorable Representative Binks:
"He goes back to Naboo and he's a representative. He probably stays on the council, he's probably in the senate, because it becomes completely worthless. Senators are just for show, which they talk about in Episode IV. Actually, in Episode IV they get disbanded, so Jar Jar probably goes home to his wife and kids."
On the TV series and the future of Star Wars:
"I love doing it, but it is 20 years of my life," he told Static Multimedia. "I am anxious to get on and do other things. We are still doing a TV series, two TV series, one animated and one live action, so I am not going to do it myself, but I'll peek in from time-to-time. So I won't completely have lost the Star Wars experience."

So there you have it. I interpret this as entirely Clones until sometime in the OT period, when they start putting conscripts in there too.
