Prius (2004-09) :: 2006 - Low Beam On Passenger Side Headlight Stopped Working

I have a 2006 Prius that I purchased with no upgrade on the headlights. There was an upgrade available for high intensity lights, but, I didn't get them. The low beam on the passenger side headlight just stopped working. Two questions:

1. I was just told by the Toyota dealership that to replace the headlight, the entire front end of the car would need to be dropped. They just told me that with them supplying the bulbs, the cost would be about $250 plus tax. If I supply the bulbs, only about $200 plus tax. My owners manual indicates that this is a do-it-yourself project. Is this true or is the dealership trying to make money off of me?

2. When I do replace the lights, I would like to put in something that would put out more light than what I have now. I have been told to be careful because many replacement lights throw off so much heat that the housing around the bulb could melt. Also, I have read that some of these replacement bulbs have a very short working lifetime of 1-2 years. Obviously, I would want to keep away from them.
