Wait for finals to apply?

Hi everyone, I’m in my last semester of undergrad and I’m trying to figure out when I should submit my applications. My final grades come out on 5/7 and I’m taking the GRE on 5/21. My application is done except for my final transcript and LORs.

Should I wait to request my final transcript until my final grades are in? And should I wait to apply until then so that I can finish my unofficial transcript on CASPA with all my grades being completed?

Also, should I submit to all my non GRE schools before the GRE and the rest after?

I have been trying to find other posts on this but have struggled so I would love to hear everyone’s advice! Thank you!
