You are complaining the bike is too long, and you plan to install a longer stem? Bravo!
A shorter stem would be compensating for a too-long top tube .... and News Flash---That is why you would use a shorter stem.
But whatever. Keep keeping us posted and try ibuprofen for the back pain. The rest of us would adjust our set-ups, but you don't have to. We value individuality.
Good to see you are still around.
