Funny, yeah, Bose is probably not the way to go! Other than great commercials, they are not teribbly respected in the AV world. Finding the perfect set of speakers was, for me, the most fun thing about the home theatre experience.
For a receiver, I would strongly recommend going used or a year old model. They are always putting out new models, without necessarily any improvements. Just make sure it has the connections you'll need (DVI, HDMI, etc).
