how to get users's rank in a specific leaderboard?

Trying to understand the "gameNetwork.request( “loadScores”, … " method at the moment.  

Q1 -  Does this actually return the scores of the top ranked players then, based on the range?

Q2 - How do I get scores back for just the local player?  In particular what I really want to do is get back:

* for leaderboard X (i.e. specify the board - e.g. Level12_BestTime), for given TimeScope

* get returned the local players current:

  a) time e.g. 12.3seconds

  b) ranking (with Friends)  e.g. 12th

  c) ranking (All players)  e.g. 123rd
