It's difficult to know what kind of weights to suggest when we haven't seen you in action (probably never will, given the distance!), but I'd recommend a good personal trainer- preferably one with a NASM certification, since they are the best ones out there.
I don't know of a website where cyclists post their power stats online... perhaps Danno may know of one?
In my opinion, I don't think a standard criterion for strength can be used for individuals. When I train people, I train them as individuals- I feel every person is different and should be trained as such. It helps the person to focus on their goals and not someone else's. But that's my two cents.
