What 32-bit browsers?

You shouldn't have any.

Get rid of the 32-bit version.

JavaFX is not Java.

JDK is the developer toolkit. JRE are the runtime JVM invokers.

There is a JRE in the JDK.

Did you read the information on the *Oracle* website? 

Read that first, and understand it, before you start to rely on 
third-party sites like mindprod.

Uninstall the ones you installed. Re-install the 64-bit JDK.

You shouldn't need to do anything special with the PATH 
for a Windows installation.

The Java installation doesn't include anything in startup, and 
really, why should it? 

It doesn't create any desktop icons, either.

You can create an association in Windows between JAR files and 
the "javaw" JRE invoker, but for development you use command-line 
tools (like direct invocation of the "javac" command or Ant) or an IDE 
(Integrated Development Environment) like NetBeans or Eclipse.

As explained in Oracle's Java tutorials. You *are* studying the tutorials, 
aren't you?

RTFM.
