T-Shirt removal hint.... Assuming you aren't doing this already.... Bend over. Lift good arm over your head/shoulders to back. Grab onto T-shirt on back and pull arm back over head to front. Should bring shirt up and over. I've been wearing T-shirts since I got my arm out of the sling around 6 weeks.
As for other activities, I was doing well by eight weeks despite the fact that I got behind due to a therapy mess up. If you aren't doing them, I highly recommend isometric strengthening exercises to go with the stretches.
