Two-and-a-half questions (if the second is better in another thread, please feel free to point me there )

1. I current have two United Club passes in my iPhone app from my Chase United Explorer card from renewal last May. If I cancel the card, does Chase somehow claw those passes back?

1a. If I let the card renew May this year, I presume it will load two more passes. If that happens before 30 days after the renewal date, can I cancel the card and keep the passes?

2. When searching United award inventory I get the enhanced availability because my Explorer card is in my profile. But I also have a "basic" United card that has no fee. I know it comes with no free bag allowance, but does it come with a) priority boarding, and b) enhanced award flight results?

TIA!
