That all depends. Every Jeeps seems to be just a little different when it comes to this stuff. Some doing the bl/mml at the same time don't need the TC linkage drop bracket, and the instructions say that too, if I remember right. Mine kept popping out of 4lo even after adjusting the linkage, so I used the bracket and did not have a problem while I still had stock linkage.
A MML will slightly help with driveline angles as it lifts the front of the motor, and causes you tailshaft to tilt down slightly. Will it be enough to not need a SYE/CV shaft or a TC drop? It all depends on your Jeep and what lift you are running. For my Jeep, I had a slight driveline vibe after installing a 2.25" BB as my first lift, the MML cured it.
