Joomla Community Builder customization (Revised)

I have revised this project back from previously posted CB profile custom fields, I have developed a sports tipping website integrating J-Tips and Community Builder as the main components. J-Tips is (now) an open source component which I have configured to my needs I just need to integrate some of the user statistics into Community Builder so I can customise lists and Profiles to display key fields. I am using Groupjive to allow users to create and join leagues (groups). The main integration is using custom CB lists to display USERS in the VIEWER'S leagues. I have written a detailed brief attached. There are 3 elements to the project all I believe are very strait forward for someone with solid PHP, MySQL skills and a good understanding of CB and Joomla. Please feel free to ask any questions.
