Im a little confused here, I rewatched Ultimate Note (Because Why not) and If Ultimate Note is supposed to happen before Tomb of the Sea, how come in Ultimate Note, Zhang Qiling is supposed to have returned from the Bronze Gate? and in Tomb of the sea, he is still behind the gate.

Zhang Qiling went into the Bronze Gate twice between those times. The first time he went in he was gone for several months (after The Lost Tomb 2 and before Ultimate Note) and the second time he went in he was gone for 10 years (during Tomb of the Sea and before Reunion).  

I also was confused as to the order so this is a huge help.

When should one watch The Lost Tomb Pilot (prequel) ??

The prequel listed on MyDramaList is just the first two episodes of The Lost Tomb. It might be edited slightly different, but that's it. You can just start with The Lost Tomb
