Theres some good info about Owen Lars at the Star Wars.com Databank:

Apparently Owen thought Anakin should have stayed with his mother on Tatooine and not gotten involved with the Republic or the Jedi because of the affect Owen seen on his step-mother Shimi of being without Anakin.

Well that nice. Too bad Owen's thoughts aren't actually in the film and we need 3rd party source to clarify that.

I always thought there was some kind of big blowup between Owen and Obi-Wan offscreen, I imagined Obi-Wan bringing Anakin's Lightsaber to give too a young Luke but Owen refused and ran Obi-Wan off and told him to leave Luke alone and never come back. It would have been funny if Obi-Wan waved his hand at Owen and said "you will let me give Luke this Lightsaber" Owen: "I will let you give the Lightsaber to Luke." Obi-Wan: "oh, by the way you will let me sleep with Beru"
