That sounds alright, though you can increase to 2 cups of greens. The types of greens you mentioned are all fine. It's a good idea to switch things up now and then by trying out some different greens depending on what's available. Basil, parsley, red or green leaf lettuce, are a few other options to add variety.
As for the pellet amount, each rabbit has different needs depending on exercise, etc. Some smaller rabbits may need a bit more than the 1/4 cup pellets if they start to get thin.
I just linked the following article on another thread today. It explains about when 1/4 c. pellets may not be enough.

Because of several potential problems associated with pellets, some veterinarians now recommend that pellets be not only rationed, but rationed quite severely. Instead of giving the rabbit all she can eat in a day, a night, or a few hours, we have been considering the following amounts as maximums (Brown 1994):
5-7 lb of body wt. 1/4 cup daily
8-10 lb body wt. 1/2 cup daily
11-15 lb of body wt. 3/4 cup daily
There is evidence that small breeds (under 2 lbs) may require a diet higher in energy and lower in fiber than the larger breeds (Cheeke 1987, 324). Several foster homes have experienced digestive problems in rabbits under 4 lbs who were put on severely restricted diets.
Once pellets have been reduced, it is equally important to make sure that fresh grass hay is available to the rabbit at all times, and that fresh vegetables be given in larger amounts than has previously been recommended (up to 2-4 cups a day).
