Answer 1

When added as a library, lwuit is only available for your application to compile against. I assume lwuit is not already installed on whatever J2ME-enabled device/emulator you want to run your application.

When added to your application jar file, lwuit is also available for your application to run against. Your application jar file is presumably significantly larger then.
