I forgot to mention that for the groupset change, you will need to replace the rear wheel at least. Might as well sell the current wheelset and get another 9/10/11 speed compatible wheelset. Judging from the frame size the OP seems to be taller than I am. So would recommend 32-spoke x3 wheelset for front and back for indestructable daily riders. Or 28-spoke x2 for something a little more sporty.
