Trek 400/460 solidarity!
-and yeah from my experience that sounds like you might have cracked or broken a rib or two! Nothing they can really do for you at the hospital other than charge you money. Atleast you're not a kid and dont have to worry about related growth problems if you did break something.

From what I understand the 460 was marketed as a training bike for professional racers or an amateur racing bike. This might mean that the 400 was meant as a 'casual' racing bike. My assumption is therefore that the 460 has steeper and more race-like angles than the 400, but probably not by much.
