Wordpress custom user profile page

I would like my WP blog users to be able to update their own profiles without using the builtin WP dashboard. What I'm looking for is a single PHP file that I can drop into my theme folder that supports the following features: 1. Display user profile information * user name - read only * first name - editable * last name - editable * nick name - editable * email - editable * new password/confirm password - editable * PLUS - I used Register Plus Redux plugin to add a few custom fields - telephone and address fields. Any other fields I may add in the future should automatically be added to this page. 2. Ability to save changes - full page HTTP POST is ok although AJAX POST would be a plus! Anyone who has already done something like this (and can show evidence) would be given a preferential consideration. I would've loved to be able to use Customize Your Community plugin except it doesn't seem to work with WP 3.x (which is what I'm using) and also the developer seems to be out of pocket.
