If its not going to be street driven and will be a track only drag car, then cage it. Best way to stiffen up the chassis and provide protection.

Most tracks seem to require a cage if the car runs less than 12's, so if you plan on that, then you'll need to have a cage built anyways. unless you don't plan on doing your drag racing at an actual track......

Traction bars and some stiffer motor mount inserts will help reduce wheelhop at the front. Dampers with some more rebound in the front, and stiffer springs + more compression in the rear will help with squat.

A good thread on traction bars:
https://honda-tech.com/zerothread?id=1183730

Energy suspension makes polyurethane motor mount inserts that many people seem to use with good results.

I can tell you what to look for in the shocks and springs, but you're asking the wrong person if you want brand names. Generally, the higher the spring rate in the rear, the less the rear end will squat. It is not unheard of to run 1000+lbs/in springs in the rear for a drag car. But that will be undriveable - figure your car has something like 150lbs/in springs in the rear stock or something (not sure of the exact #). The shocks should simply be valved with greater rebound in the front and compression in the rear ("greater" meaning more; more rebound is more resistant to the extension of the shock, more compression is more resistant to compression of the shock).
