2000 gtp - crank sensor replacement

It looks like my crank sensor is going bad. The car runs fine, but every day back and forth to work, I loose my tach and the tcs goes off. My question is: If the crank sensor is being replaced, is there anything else that should/could be replaced so I do not have to pay for the same labor. As if you did not know already, the engine is the 3.8 w/ supercharger.
Thanks for your response in advance.

other than doing an inspection of the wiring harness to the CKPS, that is all that needs to be replaced. Check the serp belt while you have it off.

depending on your milage, its probabaly a good idea to inspect the balancer. I think mine is starting to go bad becasue when I turn my car off sometimes I hear a few metallic clunks as the motor slows down.
