MrBankRoll: I do not subscribe to the gruesome Druid practice; you can study that on your own. There is a literal cornucorpia of varieties (species and subspecies) of pumpkins. Pumpkins, probably more than any other gourd, require proper agronomic practices. They are quite susceptible to range of blights and other fungi. If one is only looking for a few in number, raised beds will often prove their value. Depending on your zone, you have roughly five secure weeks of growing left. For what you want, you might as well clip the empty vines.
As to zucchini, I personally favor them rather small, since I enjoy them raw or lightly sauted. For you stuffing fans, remember the seeds can be a bit tough. By quickly picking the small fruits, a bounty of new flowers appear.
"When in doubt, empty the clip."
