To attach an NPC to a layer, first select the NPC that you want it to be attached to, and put it in a layer, which can be named whatever you want. Then pick another NPC, that you want to attach to the other NPC, then open the "Events" window, and where it says "Attach to Layer", pick the layer that you put the other NPC in. So, for instance, if you want Mother Brain to follow you around like a Lakitu, select the Mother Brain, and put it in its own layer. Then select the Lakitu, and open the Events window. Where it says "Attach to Layer", select the Mother Brain layer. Always put the stationary NPC in its own layer so the moving NPC can be attached to it. Never put the moving NPC in its layer and attach the stationary NPC to it otherwise it won't work.
Making an NPC invisible is simple. Select the NPC, and open Paint.NET (assuming you have it). Turn the entire thing black, and save it in the level folder. Then open the mask for the NPC (it has the same code as the graphic but with "m" at the end) and turn that white. Save that to the level folder, then save the level afterward. However, not all graphics will have masks, so you can only make certain graphics that have masks invisible.
And about nogravity=1? Just open a Notepad file and put "nogravity=1" into it. Then save it as the name of the NPC that you want to have nogravity=1 on. Then test the level. The NPC will be unaffected by gravity.
