Resolve or Close option should be available only for Ticket owner or Group member of the ticket's group.

Hi, I need the help of the ServiceDesk community to solve a couple of tasks that I am stuck on.
1) Configure the system to restrict other group technicians from resolving/closing incident requests raised by a VIP user, once approved.
2) The Resolve or Close option should only be available to the ticket owner or group member of the ticket group
3) Create a general survey after each major change implemented in the org and record the feedback in Review as Post implementation feedback from org users.
Thanks
