Help a newbie girl in displaying comment & other widgets

I am pretty new to WP and loving it. Need a little help from the veterans. I have searched the widgets and plugins and sort of lost with choices. What I want is a stable (and close to WP core) widgets or plug-ins to show in the side blocks / side bar of individual bloggers in a wp-mu site, these being visible to the public in general (not just admin roles) :

A side block that shows individual blogger’s photo & intro
Total posts and comments made by the individual blogger
Recent comments received on the individual blog [ Comments I got]
Recent comments made by the blogger on all blogs[ Comments I made]
List of favorite posts of an individual blogger [ My favs, visible to all]
An archive in calendar form for individual bloggers

Thanks in advance.
