Is there any plugin that…? >>> Pls help!

Is their any such wordpress plugin that can make manage my user/members list?

Specifically like,…if one user which is a ‘member’ login and visits to his dashboard then, there would appear a unique menu called ‘Members’ (since he/she is a member) as one of the dashboard’s menu. However, if another kind of user, let we just say his/her role is a student (note: i made these kinds of user-roles – MEMBER and STUDENT in my site including the rest default users…hence, user which is a ‘member’ and the user which is a ‘student’ is NOT THE SAME THING, whereas the registered ‘members’ has greater priviligers other than the ‘student’) so the menu that would appear is now ‘Student’ (not ‘member’ anymore becoz the user login as a student. Then within that menu, there contains the list of all the user (active or not). The list would preferably shows as an indexed table with the names and other basic infos of the user in relate to his/her role in my website.

Well this sounds difficult in my part becoz it seems i would really make a plugin for this…hehee LOL(not definitely a plugin but just a some kind’a codes to be created to form what i wanned, right?)

HOPE ANYBODY CAN HELP ME RESOLVE THIS!
just post here and give me some informative links, codes and scripts that can be a great aid regarding to my problem.
