I think you need to do 2 things.  Or maybe just one of them:

1) I think you may have put the "plus" firmware (UM2+) on a UM2.  Double check that you put the right firmware on your printer.  The UM2 has a black feeder.  The UM2+ has a white feeder.

2) Do a "FACTORY RESET".  It's in the menu system somewhere accessed on the front of the printer.  I can explain more about this if you want.  

 

After doing those 2 things most of your issues should go away but possibly not all.  You might want to remove the glass for now until it seems like things are working although I've had the glass slam into the nozzle and never gotten a scratch.
