Cherie,

You're going to love that set of clubs. A gentleman that I work with ordered the same irons and absolutely loves that shaft/head combo. As far as matching wedge shafts, is always best to get fit. I've reshafted a few wedges for customers, using A flex graphite shafts and they like their performance. However, you may be fitted for, say, a soft stepped R flex steel shaft in your wedges, due to the fact that one rarely takes a full swing with their wedges. You want control with your wedges. 

As a testimonial to David's recommendation, I much prefer my steel shafted 48 Vokey wedge to my AP1 A-flex PW 45 around the green (anything less than a full swing) for feel.
