Yeah. Check with your doctor about ramping up the intensity/etc, but don't wait for a number on the scale to start hills. Base your highest effort level (either hills or intervals) on where *you* are -- don't give yourself a heart attack, but unless your doctor says no, push yourself a little. You'll get stronger quickly. (Ugh, I need to start doing my winter hill training. Do as I say, not as I do.)
Group rides will be rough at your weight because if a group is averaging your speed, they'll be slower on the flats and much faster uphill. Unless you can find some other big guys/gals to ride with.
