Unfortunately removing diseased leaves is the only means you have of slowing the disease's spread. For that matter, the disease is defoliating the plant anyway, so it's one and the same thing. No one knows how many healthy leaves a plant needs for sufficient photosynthesis but the question usually becomes academic anyway if the disease has a grip.
Undeveloped fruit isn't uncommon. I've got some on a couple of my plants. It's a pain in the backside in one case because I need to save seeds from that plant this season. Blossom drop can have many causes - lack of pollination, too much humidity, too much fertiliser, and so on. I tend to get it here because of excess heat. When the temp is 42C+ for the plants, something's gotta give.
This could be a tomato annus horribilis for you, Gard, which would be a shame. Unfortunately it's part and parcel of growing toms. I've had more than my share.
