In short, J2SE is an acronym for Java 2 Standard Edition, which comes in
different flavours. If you just want to be able to "run" Java applications
you just need the Java Runtime Environment (JRE) of it. If you want to
develop things in Java, you want the JDK (Java Development Kit).

As you're new to Java, stay away from J2EE for the time being. J2EE is the
Java 2 Enterprise Edition, which is an *extension* to J2SE, and supplies
foremost server-side technologies, such as Servlets, JSP and Enterprise
Javabeans.

To develop applications and applets, you just need the J2SE JDK, not J2EE.

For you to be able to run server-side applications, as mentioned above.

For the Netbeans questions, someone more familiar with that environment
possibly could answer that question.
