First of all, the 3 degrees upright lie angle WILL affect your play! Positively or negatively, who can tell, since you haven't been fitted. Blow the money and take your chances, or get a fitting?
You seem to be impressed with clubhead speed. Clubhead speed doesn't mean crap if all you're doing is hitting the ball farther IN THE WRONG DIRECTION!
Take WUT's advice. Find someone who knows how to fit a golfer for clubs and get, at least, a wrist to floor measurement. This will get you a starting point. Hopefully this person will get you past that to lie angle and beyond. Lie angle is VITALLY important. My buddy has clubs he bought somewhere, and the lie angle is much too upright for him. When he addresses the ball the toes of his irons point to the sky! He's 5'8", but he needs to be 6'2" to play these clubs!
Another vote for "breaking 80." I've had several rounds of 83, one of 82 (technically match play, but no putts were conceded to me beyond literal tap-ins), and a few other 84 and 85. I've never broken 80.
I feel like I have had at least one round without a double bogey, but I can't recall the exact date(s). I suspect if I set out with that as my goal, I could set up a plan to do so at my home course. By contrast, I have yet to exhibit the sustained good play needed to break 80.
