valve cover gasket - don't know, never head a problem with that.
transmition gasket - well, you'll want to change your fluid also. And if it's automatic, then filter too. For auto, probably about 200CND, stick, depends what kind of oil do you want to use...anywhere btw 50-100CND.
Water pump, on my 2.5L was 400CND on dealer.
Spark plugs for 2.5L 50CND
plug cables for 2.5L 150CND.
next time specify what engine and trans do you have. It all varies.
good luck!
