I went through the following process. Was productive for me:

1. Swing lessons
Had 3x4 video lessons & determined what I wanted to do about my swing. Result was a major swing plane change.

2. Fitting
Went to a club fitter. Sacrificed my 6-iron. He adjusted the lie according to the new swing and - in my case - plugged it to make the shafts longer.

3. Trial period
Played that 6-iron extensively on range & course for 2-3 weeks. It was obvious it was right for me.

4. Full re-fit
Alterned grips, made lie adjustments & extended all clubs by a shaft butt plug.

5. New set
Got a good deal. Bought a full new set of irons. The old ones had been with me for 7 years.

Conclusion:
Make sure you know that you are swinging the way you want. Then adjust the lie on one club before anyting else. Try that club for some time before making further changes. In your case you might want to take off 0.5 inch on one club. If it does not come out the way you wanted, just have a 0.5 inch plug added.
