Some fine advice already offered, but I would have to add: think about what you want. Audio is really changing, and you should ensure you're getting something that will serve your desires (we aren't really talking "needs" here, right? -smiley here- )
Sources:
CD?
Mass storage (from download, burn or "local creation"/recording)?
LP (who know how long the fad will last)
Streaming?
Amplification:
Phono input needed? Or "line" only?
Digital only?
Analog and digital sources?
Output:
Speakers?
Headphones?
Depending on those "desires", you might avoid entire components you don't need. An amplifier, a phono input, component CD player, A/D converter...
