Tickets

I sent in my order for Post Season tickets but I'm assuming they were never printed. Since I'm a season ticket holder of 3 years. I understand the money goes toward my 2 season tickets next year. I have two questions... What do I have to do to get upgraded tickets (closer to the field)? Is there a list or do I have to wait until you have an open house? Presently Section 147, row H, seat 18/19. I always miss the open houses because of my work schedules, so when I can get there, all the better seats are already gone. I would also like to order extra tickets for one or two games. Am I required to wait until those are available to the public (non-season ticket holders)? I've been obtaining them through scalpers... and found tickets out of town easier to obtain, ie... New England, Atlanta and Miami.
