Will this bolt straight into my car without any adapters?

Yes. This radiator uses factory mounting points—no drilling, no custom brackets. Bolt it in place where the old one was.

Do I need new hoses and clamps when I install this?

The radiator assembly itself is complete. Inspect your existing hoses for cracks or brittleness before reinstalling; if they're worn, replace them while you're in there. New clamps are cheap insurance.

What coolant should I use after installation?

Refer to your owner's manual for the correct coolant type and mixture ratio. Flush the system before filling to remove debris from the old radiator.
