No struts on the Crossfire, just springs and shocks on all 4 corners.
The KYB's seem to be the weapon of choice.
Replacing the shocks will not require alignment, but with 128K on it, it wouldn't be a bad idea to have it checked.
( Check the front lower ball joints too )
The steering stabilizer shock is cheap, an easy DIY and most replace it every 30-40K.

If you are gonna lower the car, then there are lots of considerations - search the threads here on lowering.
