No clue which of those numbers are the frame number. In what format are the
one for you guys?

I can't tell you what the frame number looks like (though I bet you
could contact a Trek representative through this form and ask:
http://www.trekbikes.com/inside_trek/contact/index.jsp ),
but I can tell you that the serial number on my fuel 90 is:

WW####### (Two W's, 7 digits)

It's also prefixed by S/N.

So by process of elimination, anything that looks like that isn't it.
