I used TJA1042T at first, but now I replace it with TJA1042T/3.

Besides EMC,is there anything special I need to test?

SPLIT can help to stabilize the recessive voltage level on the bus,TJA1042T/3 no SPLIT,does that make any difference?

Yes,you don't need SPLIT function and also don't need consider performance about this PIN.

According the reference schematic to design your circuit!
