The submarine you are thinking about was the USS Nautilus. It was the world's first nuclear powered submarine and commissioned into the US Navy in 1955
No japan did not have a submarine that could launch aircraft.
Pearl Harbor was one battle. The most important facts were the USA aircraft carriers weren't there and the Japanese weren't able to attack them, so the carriers led the way to victory against the Japan. Also, Japan only launched two air strikes against the bases at Pearl Harbor. If they had launched a third, they could have bombed the oil reserves, the dry docks, and the submarine pens, and further hurt the USA ability to strike back.
yes
The Trieste was that famous submarine. It is actually considered a bathyscaphe, but the term submarine could be applied. It dove to the deepest undersea point in the world, the Challenger Deep in the Mariana Trench, where the water depth is nearly 36,000 feet. A link is provided to the Wikipedia article on this revolutionary undersea vehicle.
People could travel farther and more frequently. Also, rail travel was safer

A submarine is used as a subsurface naval weapons platform, or as a tool of exploration and recreation. The latter may be manned or robotic, and have a wide range of characteristics and applications. They are usually operated from or with direct reliance on a support vessel of some kind. We've seen them carrying investigators to the deepest oceans, or surveying shipwrecks on the bottom of the sea. The former are usually sophisticated naval vessels capable of great range and extended independent operation. They can carry torpedoes to sink other vessels, or guided missiles to be launched at distant targets to deliver nuclear payloads. The newer munitions include cruise missiles which can be launched from the submarine, or anti-ship missiles which can also be launched from below the surface. Certainly there are a number of instances of "spooks" working with the submarine service in a number of espionage or "black ops" projects. It could be the insertion of a SEAL team, or the gathering of intelligence in various ways.
They could travel by land or sea across Panama or around Cape Horn
Not by any commercial transport. Most travel was on foot or horseback.
You could travel around the world 4 times.
