Just watched some StarWars movies again. Preparations for eopisode III perhaps, I dunno... :P.

Anyway, there are three things that are bugging me (from ep II mainly), perhaps someone here is a hardcore StarWars fan with all the answers.

1) Jango Fett was the "host" for the clone army that was created for the republic, however he was fighting on the other side. Why be the host then? Seems stupid to be responsible for creating an army for the enemy!

2) Count Dooku/Darth Tyranos is leading the war against the republic and tells about the Sith infuencing the council and how he must be removed. The Sith is obviously Darth Sidious/Palpatine that he works for, but why organize a war against the republic if he's already the senator/emperor/whatever? Also, was Nute Gunray truly in belief working against the Sith or was this a lie from Dooku?

3) During Ep I & II (possibly III too) C3PO has been in contact with Obi-Wan, Anakin and been on Tatooine multiple times. However in Ep IV (the first movie) it seems he's never met Obi-Wan before, nor been on that planet. Getting a permanent amnesia in Ep III?
