The back end should not lift like that during braking. Do the struts bounce at all as if they are blown? There are lots of strut options out there. I loved my KYB AGX adjustable shocks when I had my Integra, and Koni Yellows are also a good choice. I've had bad experiences with Tokico, so I'd stay away from them. Stiffer front springs would help too, as the nose wouldn't dive as much under braking.
Also, why are you braking mid-turn? That's asking for trouble.
