I'll take these one at a time:
1. Padme's subterfuge: she went with her own name because Glup Shitto was taken.
2. The giant room: Due to the lethal and destructive nature of lightsabers, Galactic Republic building codes mandate a designated "Lightsaber Dueling Chamber" to prevent collateral damage and general disruption of day-to-day activities. See also Cloud City.
3. Palpatine's plan. True, but he doesn't subscribe to the old adage: "Given the opportunity, tyrants will optimize the fun out of taking over the Galaxy." In other words, it's the journey, not the destination. Let him fly free!
4. Windows XP background fight. The gungans got into Microsoft at $1 a share.
5. Droid factory hurting eyes/brain/soul. Yes, but your earlobes, elbows and toes are fine! With just a little more effort Lucas could have gotten a clean sweep.
6. Jedi saber techniques. Their efforts might seem uncoordinated and lackluster to the untrained eye, but they are practicing a highly-advanced lightsaber form wherein they defend against attacks and opponents many months before they are added in post-production. Truly, the Force is strong with these Jedi!
7. Long-necked Jedi. Disadvantage at swords and starfighters, to be sure, but a 100% advantage with those alien ladies, which as a Jedi he can't take advantage of, so uhh...yeah, bummer dude.
