Chris i can help you with goal number one i am actually doing the same thing with my equipment, changing out my irons only! But i have two sets for sale if you want to discuss!
however my goals in no particular order are
1) Break 80 at my home course par 72
2) Beat my dad twice, i am 30 years old and have never beat my dad i have come close but he is really consistent and my ball striking has not been consistent for awhile. I am pruchasing a nice set of ping eye 2's and have a new driver.
3) I want to hit 300 balls a week starting end of march. I need to find a swing net for my garage. I think this item alone will help me start scoring a lot better and it not the equipment. But i am switching to a more forgiving iron.
4) I want to get my handicap down to a 15
5) Get my two year old daughter swinging a real club she seems interested but do not want to push her if any dads have any good ideas let me know i am just going off how my father taught me, which worked out well, i love to play!
6) Get my wife to play one hole of golf with me, this could be a tough one but she has gone to the range with me! Her hand eye coordination is not the best but i like teaching her how to swing!
