Will I need new gaskets or hardware to install this?

You'll want fresh exhaust gaskets for a clean seal at the flanges. Bolt-down hardware should work with what you have, but grab a new gasket kit while you're at it — they're cheap and prevent leaks.

Does this system include the resonator or is it straight pipe?

The system is designed as a full catback assembly. Refer to images and fitment notes to confirm if a resonator is included in your version — construction details vary by production batch.

Can I install this myself or do I need a lift?

Bolt-on design means you can do it in a driveway with jack stands and basic hand tools. Most owners knock it out in an afternoon. Make sure you let the old system cool completely before touching anything.
