G'morning Joe,

definitely read the link provided by lfalna, it should help quite a bit.

as for your questions...
1. you must create wow macros to coordinate your targeting. this is discussed in : [Keyclone] step-by-step wow macro setup (level 1.5)

2. how to set up maximizer? your link helps define the steps. there is also a setup video available here (link )

3. you need to add your movement keys to your do-not-pass list (keyclone/setup/do-not-pass)

4. the macros forum

5. yes, multi-boxing is perfectly legal. the only thing people get into trouble with would be 'account sharing'... meaning you are using accounts that are not in your name.
