I understand that if it’s Above 640 Mgm after 2020 it’s no good??

To be safe anything in the 600MHz band should be considered restricted when it comes to wireless mics. Check the FCC website for details

Do i need shure blx1 bodypack transmitter, h9 for this mic?

Whichever system/components you choose, you will need to ensure all components have matching frequency bands in order to use. The BLX2 handheld microphone itself is the transmitter so you will not need the BLX1 body pack transmitter. The BLX1 is only for headsets and lavaliers.
