The reason I bring up Alderaan is because, according to the Radio Drama for ANH, it is one of the key systems making up the Empire. That, along with its destruction (because dantooine was too remote to be an effective demonstration) said to me that Alderaan is both politically and cosmologically (the space equivalent of geographic?) more prominent than Naboo.
What this all really comes down to is that I wish George had spent a lot more time planning his prequels. Sure, he had notes and ideas from way back, but when it comes right down to it, these prequels, story wise, have not been terribly well thought out. Too many inconsistncies with the OT which they have to link up, too many internal problems. I really wish he'd written all the scripts first, and then started film, instead of doing one, filming it, then writing the next. Not to mention, I really wish he'd gone the route he did for the original trilogy, that is, writing the story, but leaving the script to professional, talented screenwriters. George is a good story man, but not a good writer. Why he continues to write them himself is a mystery to me. Oh well.
To me it feels like GL wrote the PT without going back and watching the OT. It feels like he said "I made those movies, I remember them well enough" and just started working on the new stuff. It's the only real explanation I can come up with for the inconsistencies.
As for Steve Sansweets job, yeah, that'd be sweet. Honestly, I think George could find someone better. Nothing against Steve, he's a good guy, but I've seen SW fans online with hugely comprehensive sites tackling the most mundane of minutia in much more logical and believable ways than I've seen come out of lucasfilm.
