JFBConnect should work with AUP 1.7.3 for awarding points for Like's, Comment's, and Requests. We don't have other integration available, if you were looking for something other than that. Our testing was with AUP 1.7.1 (or .2 I believe), but .3 doesn't add anything crazy.
Hope that helps, but if you need info on configuring or enabling the points, just let us know!

Just Installed - Will Work With AlphaUserPoints 1.7.3?
