My 2 Pfennig:
Allow yourself some time to get comfortable with the game. It's bound to become much more challenging!
As a Pro, you play very good and expensive balls. The only downside is that they fix you to slow meter equipment. Unless there's any personal challenge making this inevitable, try faster and cheaper equipment - you will probably get used to it.
Ball recommendation: Tour-SD or Srixon.
IMHO, it's much more important to improve the short game than the long shots. You might get two short ATV wedges now, or the budget alternative of Ping wedges in a few days - ehm - levels.
Concerning the long irons, consider the R11s whenever you are ready.
