JRE in this case means blackberry jde version. So it defines the the framework version and targets OS you are going to develop apps for.
Complier compliance level is java compiler setting which has different versions depending on jdk version. By switching to different compliance versions you can use the appropriate syntax in your code(java 5 level with generics , or minor versions for ex.).
To develop for BlackBerry you should use 1.3 compiler level.
JRE usually means the Jave Runtime Environment, and is the runtime component of the Java level installed (i.e. what you need to run Java programs). JDE is the Java Development Environment, which is a standalone IDE developed by RIM.
Youcan install as many JDE levels as you like, you must use the version that matches or is 'older' than the target OS level.
In Eclipse Plugin 1.1, they name the packs JREs. I think this is what he is seeing if I'm not mistaken.
