We are using AlwaysOn to a DR site so we do have High Availability

The 2 hour restore is if we lose both it has to be available within 2 hours

Overkill?

Nah, business requirements. Whatever they are is what they are as long as they're physically possible and within the budget being provided. But, it does sound like you might be solving one problem and introducing a second with partitioning. I'd recommend some VERY thorough testing around these changes, especially dropping the FKs for triggers. I think that one is crazy, especially if you're already experiencing performance problems.

No, but I'd probably consider something like log shipping to a tertiary (maybe an hour behind primary) for the 'must be up in 2 hours', rather than jumping through hoops with tweaking backups. But then, last system I worked on with requirements like that was over 1 TB and restoring backups was a 4-6 hour process.
