Do i need a park pass to access the beach or park? And do i have to be a resident to gain access ?

Kraft rd beach is free but limited parking. Can walk to Lakeside from there.

Tried to go the other day and showed my license to show I was a county resident but was told it would still be $20 for the day

no, you just pay the fee.

Yes, 5 bucks for day 35 for year. Thats non residents price
