Kick Panel installation

[pound41]

I have my b pillar done. I have the inner rocker and rest of floor pan patches screwed in place. My kick panel patch needs to go above the factory cowl/windshield to floor pan seam. Also my a pillar replacement cut is higher up than the kick panel cut. So here are my questions:
What did you guys use to cut out the rotted kick panel especially where the kick panel meets good floor?
Did you cut your kick panel and A pillars in the same place?
Does the kick panel sit down on the floor pan or is there a desired gap?
Is there any correct order to replacing most of the floor pan?
Does the inner rocker go 1st or does the kick panel?
Any help is appreciated!
Thanks
