Your results look better than my early prints! Keep going and you will get better. Grade 2 is the standard contrast paper in my experience. I did most of my prints on Ilford Multigrade paper which allows changing contrast with a filter so you don't have to keep different grades of paper. Try to get an electric timer, as Erik said, to improve consistency. You may get sharper prints with a Nikon or Rodenstock enlarging lens if you want to spend a little more money and keep your current enlarger. The Meopta are strongly made enlargers.
