As for tomato I suggest you try Dunne, if you can find the seeds or the plants. I am extremely impressed by its ability to perform well where everything else struggles and since it has San Marzano in its pedigree it should perform very well in sauce. It's not a sweet tomato so it fits the bill rather nicely.It seems to be extremely disease-resistant as well, no need to pinch the lower leaves to prevent disease. The only issue: it's a huge, very vigorous plant.
As for bell peppers... in Zone 5 you'll need to start them earlier than March since you need to "steal a march" and to have as many as possible, otherwise you'll start harvesting at the end of the season. Generally speaking Eastern European light green cultivars such as Zlutasek and Italian "cigarette" cultivars like Friggitello perform very well on a short cycle in the field but in the past couple of years seeds and plants have become hard to get by.
I am not a fan of those huge red and yellow cultivars because it's pretty hard to get them to produce nicely without a greenhouse or very favorable weather all year around.
