And as for Anakin being the 'baddest', yeah but you have Yoda and Obi Wan, and then probably 9 years later you could have begun to train Luke, thus giving you 3 powerful Jedi vs. 1 Sith Warrior. It would have atleast saved the lives of the people of Alderaan.
Let's not ignore the fact that if Obi Wan can send a message to the Jedi counsel on Coruscant, then why can't Leia or Obi Wan merely transmit the plans for the Death Star to Bail Organa? That way, you don't have to have this grand space adventure.
