Biometrics can be reused between different applications. USCIS used ones from my DACA in 2018 for my I-360 that I filed in 2018, and then reused the same ones when I renewed my DACA in 2020 and 2022.

I-485 on average takes about 2 years these days.

EAD takes like 6-8 months, so you will definitely get your C09 EAD by September 2023.
