As for the setup, the installation for extensiontables is pretty straightforward, just follow the installation instructions, they only need to be alligned the first time. I don't have a sliding table on mine, so I can't comment on that.
If you also have the wheel set, you have to make sure the wheels are facing towards the rear (as in the attached picture), in the installation instructions that came with my saw they were facing inward, towards the front of the saw,
but that way they keep the rear legs of the saw off the ground all the time, and the saw is less stable, and the legs can't be folded up properly.

The fence shouldn't need allignment as j123j already mentioned, but it can be adjusted, it's basicly the same fence as on the mft3, only the profiles have a different length. This video shows how it can be adjusted at around 9 minutes 8 seconds into the video.
