As I told you before, WTK 2.1 is recommended for the exam.
CLDC specification should be 1.1, but you need to know about the difference between version 1.0 and 1.1.
But for MIDP, it must be 2.0.
MMAPI and WMA are not optional for the exam. They are a must. If you have had a look at the exam objectives, you will see that MMAPI 1.1 and WMA 1.1 are there...
For the last question, you can use CLDC 1.0 with MIDP 2.0... CLDC means just for the configuration that a J2ME systme is built on... For more advance packages and features, we need to use profiles such as MIDP, Personal Profiles and so on...
Hope my explanation helps...
