The SVT suspension kit is great one that will really wake up the handling and not break the bank either.
I'd try calling Village Ford
, see if their price is better for it...They are a sponsor here and give us a great price on OEM parts.
Maybe look to replace some of the bushings, 165k will have worn those out too. The noise over bumps could also be the front sway bar endlinks, look to replace those with ones that are grease-able.
Normal solid rotors by centric or napa, paired with a decent pad should be more than enough for the brakes. Make sure the wheels are balance, the rubber is still decent, get alignment and you should be happy with the results.
