Not getting the Ping irons (L59+) would be a mistake, if you're going to upgrade your irons anytime soon. And unless you have a decent CDP streak going, it's going to take a bit of time to get to the levels where the better irons are.
Under level 80 or so, I think the Ping irons are probably the best irons in the Pro Shop. Additionally, I think they outperform their specs. They were the first iron set that I purchased. And I waited until then after searching the discussion boards on what irons to purchase. The consensus was get the Ping irons. They took me to Legend tier. Never regretted the purchase.
As far as putters, I would wait to Level 55 to get the Rossa or Level 59 for the Sabertooth, if you really feel that you need a better putter. I basically played the starter putter until Level 70 when I got the Versa. Personally, I think that's the better approach. Regardless, if you get the putter you're thinking about, you'll replace it quite quickly as you level up (IMO).
