Contour Enthusiasts Group Archives Forums Modifications Suspension BAT Kit and what else?

I believe I am going to be splurging for the BAT Euro Kit. My car has ~117k miles(I've had it since 60k and haven't touched the suspension, and it's pretty clunky and squeeky). Other than just getting the BAT Euro Kit, what else should I replace while it's torn apart? By the way, car is on stock 8-spokes, so wheels/tires don't change anything.
