ACman0620: if your not going pro, i wouldnt worry to much about the lessons
I'm going to disagree slightly with my friend Ron here.. if one of the reasons you stopped playing years ago was a wicked slice, the best thing you can do is get some professional guidance before you pick up the old, natural, bad habits.
A good instructor can also point you to a reputable fitter that will get you the clubs that will fit you the best.
Most of all, if you are returning to the game after a long absence, have a bit o' patience with yourself... mainly because you're gonna suck at it til you get back in the groove. =)
Peace.
