Need Assistance with purchasing a new set of irons for a beginner golfer.

I'd say go with the MX25's for sure. As Chemboy has pointed out, the MX20's are fantastic clubs that can be used by anyone, high handicap to tour players, and the 25's look very similar to the 20's. Another good reason to get the 25's is that as you get better you will be able to integrate the 32's into your set if you want a bit more playability in the shorter irons. Maybe you could even look at getting the 25's in 3-5, and keeping the 32's for the rest.
