If you practice hard, you're going to beat your first set of clubs to death. It's not important to get a new set, in fact it's almost a waste of money. You can get a top line set of irons used.

But you absolutely need to be fitted by a pro. Your height makes this much more necessary than it would for a 6' tall golfer. You're going to learn posture and swing habits that you'll have to change when you finally do get longer shafts and larger grips, so do it now is my advice.

I'd find a nice set of used cavity back irons and have them reshafted to fit you. And I'd wait a while before you have the lie changed. Your swing will evolve a lot in the first few thousand swings. The lie angle may differ after you work out your preferences.

But the shaft and the grip size are crucial.

And ABSOLUTELY get some lessons from a pro. It makes a ton of difference if you start right and learn the fundamentals.
