What is correct date for change in state residency and state taxes/credits?

Trying to figure out when my residency changed and sorting out state taxes and credits.

Change in residency

I lived in PA and started a new job in NY in May
I moved to NJ in Aug
For my part year tax returns in PA and NJ, when would be the date where residency changed?

New company paid NY state tax from start (W-2 only shows NY state taxes paid)

Should I calculate and include in the PA return the prorated NY income and NY taxes paid (for credit)?

W-2 shows NJ income (box 16) that is less than NY income (box 16) and no NJ taxes withheld

For the NJ return, should I use the NJ number (box 16) or change to the higher NY number (box 16)?

Thanks in advance for your help.

To be precise, you became a resident of NJ on the day you began living in your new home in NJ.
