To me somewhere between 6 feet and 6’ 1" is a very good height for a man. I would be very happy if I had stopped growing at this height. If you get any taller fitting into airplane seats will start to be an issue, as will some cars.
In college you get to walk a lot. This is a good time to try to get you weight right where it should be. It is a lot easier to gain weight after you leave college and after you stop growing. Personally I had to reduce my appetite by an enormous amount (roughly a factor of 2) when I stopped growing.
