Howdee Shanerjedi! Some nice ideas there (which I assume you would get over by giving the Kaminoans a language and subtitles).

I liked Magnoliafan's idea that the big ball was a holy relic that the Naboo had pinched off the Gungans.

Without any explanation that ball thing is flipping weird (here Nass shout peace while holding up a huge bomb).

The hollow planet thing must have been a dropped plotline (I thought that George was going to have Naboo turned into the Death Star or something when I first watched it).

I always thought it odd that Sidious insisted that Gunray got Amidala to sign the treaty while Palpatine insisted that she didn't.

I read that as Sidious/Palpatine wanted the conflict to be drawn out with Gunray chasing the legitimate take over line to the point where it would patently obvious it wasn't, sending the Federation out of the Republic and taking his financial chums with him.

With half the money gone the two sides would be more evenly matched and would knock more out of each other until there was nothing left but to surrender everything to the Empire.

It was something of a win, win situation for Palps, either the Queen signed away her planet's sovereign rights clearly under duress creating a scandal in the senate or Nute Gunray would be sent home with a flea in his ear making him more resentful and buttered up for the Seperatist cause.
