No. Unless you use a very old JVM, it will automatically search those .jars.
API classes are (I think) inside rt.jar. On my machine dt.jat appears to contain all the Swing class files. You will have difficulty running anything without rt.jar!

No, it's not necessary. They contain code that's used by the various tools (java, javac, javadoc, jar, ...) and other stuff used internally by the JVM. But the JVM knows how and where to find these jar files, so you don't need to worry about them.
I agree. Here's the link:
