No, the real danger only comes with high volumes or prolonged exposure to high DC offset (which may be present on a broken amp). Unless your tweeters blew or the rubber surrounds on your speakers tore, they should still be okay.
In general, yes, it's difficult to fix something as complicated as a receiver. You'd need an oscilloscope, multimeter, the service manual, and some DIY skills; even then, repair is not guaranteed and the parts might cost more than you paid for the whole unit.
