Depending on how old the string/cables are it may need new ones. Strings creep (elongate) with age and allow the cam(s) to be over rotated which can be a source of excess noise. So new strings and get the bow set to the proper ATA and brace height is what I'd recommend for starters.
Then get some limb savers and a set of Cat Whiskers. STS can help, but IMO they are over rated. Let me just say the cost doesn't justify the end results.
