Thank you for bringing your questions to the Community forum! Those are really good questions, and hopefully my answers will help!
1) The unopened list for that campaign could possibly contain unsubscribed contacts. However, if you were to add those unopens to a new list, the unsubscribed contacts will not be added to that list. They are already in your unsubscribe folder, and will drop out. So no worries about accidentally sending to your unsubscribers, that won't happen.
2) There is an advanced search feature when viewing contacts:
If you click that "Advanced" link, an overlay will pop up where you can filter people who were added after that email was sent. I recommend this filter:
Where the date field would be the date of the sent campaign.
Let us know if you have any further questions, and again thank you for bringing your inquiry to the Community forum!
