I've talked this over with friends and I've settled on a few points I'd change throughout the series:
Qui-gon and Obi-wan
Merge Qui-gons role with Obi-wan's. Qui-gon was well cast, but kind of unnecessary, we don't see him in the original trilogy so we care less and guess he'll die. Everything he does could be handled by Obi-wan and would cement his character as being far more awesome, as well showing a stronger bond between him and anakin.
Jar Jar
While it would be easily enough to just cut his character, he's kind of needed early on as a foil, especailly as there's no more Qui-gon. I'd change the character, make him less whiny and buffoonish, more of a coward and scoundrel. Rightfully kicked out by the Gungans and becomes a hero through his experiences.
Anakin
I'd have had Anakin around Luke's age when we meet him. It draws an obvious parallel between the two and makes the idea of him training to be a jedi at that age even more extreme. It makes the relationship between him and Amidala less creepy. I'd have cast a more likeable actor, someone like Matt Damon or Leonardo DiCaprio.
Heres an important thing, rather than being an emo, Anakin should have been a paragon of good-ness, basically a lawful good paladin golden haired hero. Essentially the complete opposite of what you'd expect from Vader. This makes his descent into darkness all the more tragic. Obi-wan should be the rebellious spirit of the two (hence his decision to train him at that age).
There should be hints of his darkside earlier though. Make him the one who kills Darth Maul (cutting the space battle which I'll mention later), have Maul's sabre cut in two and Obi-wans knocked into a bottomless pit. Then as Maul is about to finish Obi-wan show the other half of Maul's sabre propelled along the ground, by the force, to fly not into Obi-wan's hand, as we're lead to expect, but to Anakin's, who then stabs Maul threw the chest. A show of his early raw power and the red sabre being a implication of his future as vader.
The reason he converts to the Sith should be motivated out of two things, desire to save Amidala and more importantly that he becomes convinced that the Jedi are corrupt, beaucratic and fascistic. That being Sith isn't about being evil, it's about emotion and freedom. He should only realise his mistake until it's too late. When Amidala meets him later, she shouldn't want to run away with him still even though his killed children, she should be repulsed by him, while he believes himself doing the right thing. He kills her out of rage and confusion, then after he loses the fight with Obi-wan and is repaired, his scream should be that of a man who knows he destroyed his own soul.
Cut the space battle in the first movie
It was unnecessary and stupid. There was four fights going on at once, that's one too many (Jedi had three). It was also silly as it was the only fight that mattered, as the ship controlled all the droids, instead make it that Amidala's assault was to deactivate the droids.
Re-cast Mace Windu and Jango Fett
Cast Liam Neeson as Mace Windu, he's a great actor and makes a good jedi. Samuel L. Jackson was completely miscast in the movies. He is great as an emotional badass, not a stoic zenmaster. So make him Jango Fett, have him scream Starwars based obscenities at Obi-wan "I've had it with these bantha-fodder eating Jedis!". Then think of the implication. Every clone is a clone of Sameul L Jackson. Most badass army in the universe.

No midichlorians or podraces,

The problem is that Star Wars is very strict about keeping things in-canon. If something was made under the Star Wars name, unless it is some clearly-indicated what-if story, it's generally considered canon. Knights of the Old Republic? Canon. Splinter of the Mind's Eye? Canon. That random GBA Star Wars game nobody played? Canon. That kids miniseries involving the Emperor's (supposed) three-eyed son and grandson? Canon. The list goes on. Bottom line is this: rebooting the prequels would screw up years of story development and would effectively fuck over the Star Wars canon. It will not happen.
I thought Lucas went out and said nothing but the films was canon. Though I agree that the fanon wouldn't take it well.
