			Joe, 
 
This is the correct enforcement of the penalty in item #1.  The result of the play is a first down for A.  The USC penalty is enforced from the succeeding spot (B17)(10-4-4a). 
The line to gain is always 10 yards apart (2-25-5) unless a penalty occurs after the RFP. 
 
As far as your item 2, you wold have to ask the crew what happened. 
 
Keep up the good work!
