Few problems with new 2012 Sport Prius

Just got a new Prius with the sport package. My o5 got rearended and totaled. Right off the bat, I noticed that the 17"low profile tires had a balance problem. The dealer rebalanced them; still same problem. I went home and jacked the front end off the ground and put her in drive and noticed that both of the front tires were somewhat out of round but the LF was the worst so I put it to the LR and it seemed to drive better but still had a out of balance feel.
Went back to the dealer and this time told the service manager about problem. He drove it at various speeds and they rebalanced but the LR had to be "force" balanced. He also told me that usually, they wanted the customer to put at least 1,500 miles on the car to "round off the flat spots". This is a new one on me. Ive got less than 1,000miles so far. Then the manager told me that low profile tires weren't smooth anyway.
To make a long story short, I can still feel something out of round or out of balance. The tires have a warranty but who's responsible for solving the problem. The manager is trying to tell me that I'm just gonna have to live with it.
The other problem is noise at take off and just before stopping. I was at a friends house with a board fence on the drivers side of his driveway. I drove up and down the driveway with the window down and it sounded like a old timey street car taking off and stopping. A pronounced whine. My 05 never sounded like that. Is this normal?

 

Oh yeah, forgot another problem. The vents blow cold air out with the AC button off. I noticed this with the blower on, ac off and the temp setting below ambient outside temperature. I didn't think the ac was on without the indicator light on. Whats the deal with this?
