File | New... <Application>

Number 1 and 2 are joined at the hip.  When you create a class using
File | New Class, you specify the package name for that class.  If you
create the class first and then want to move it to a different namespace
(package), there are tools in Pro and Ent that do it for you, or you can
simply copy and paste the source to the new location, update the package
statement and recompile.

Number 3 involves getting the class file onto your classpath and that is
done by making a library for those classes and adding the library to the
project that needs them.  After that it's just your normal import
process.

Where the class lives (you really shouldn't put it in /jre/classes as
you aren't Sun and that is generally reserved for their namespace) isn't
important as long as it can be found.  When you run from the IDE, you
see the command line and its classpath in the message view.  That should
tell you the locations, etc. you need for referencing your classes.

What is the difficulty you are having, though.  Your post is a tad
generic.
