Potters & Bill Weasley / timelines

I've been lurking around in the HP lexicon looking at timelines and
things, and if they are correct at all, then Bill Weasley was at
Hogwarts at least one year in common with the Potters. That is, he may
have been a 1st year when they were 7th year, but there nonetheless.
(and chances are good for more overlap than that) Will this turn out
to be siginificant at all and is this part of the reason we don't see
a lot of him? Would he think to tell Harry, "Yeah, your parents were
there when I was?" Since we know most if not all the Weasleys were in
Gryffendor and James was too. Can he provide some insight into
anything regarding the Potters? Surely he would, at the very least,
know of James through seeing him play Quiddich (was Bill on the
team?-- I remember Charlie was.) and possibly in the common room even
if they weren't close associates. Does this also mean that Molly and
Arthur might have been there with James' parents? If this has been
discussed before can someone please point me in the right direction of
what has been said? 

Thanks!

James and Lily's background.
