Urgh. Can adding salt make the water take longer to boil? Sure, but it takes way more salt that you're ever going to (or should) use. To increase the boiling point of 1 quart of water by 1 degree Fahrenheit you need to add 3 tablespoons of salt (table salt not Kosher) - I don't use more that 1T per quart for my pasta so...
My favorite non stick pan is well seasoned cast iron. Cheap, easy to care for, practically indestructable.
Oh, and pasta should never swim in sauce (don't know if it was mentioned, I only skimmed). When you finish the dish you should have very little (1/2t to 1t) on the plate - it should flavor the pasta not be soup you're serving noodles in.
Gnocchi is wonderful if you get (or make) good gnocchi, but there is an awful lot of bad, heavy, lumpy, dense, chewy, boring gnocchi out there.
Whatever else you think of it Ben Hur was awesome because of the chariot race - they built a full size stadium and filmed all of it for real (since CGI was not a thing) - and save for about 2 shots Chuck was driving. Which leads to one of my favorite quotes... Heston was concerned about the shoot and Yakima Canutt, who was the stunt coordinator running the thing, said to him: "You just stay in the chariot; I guarantee you'll win the damn race."
