Hopefully i have posted this in the right area. I want to fully tune-up my car for example: spark plugs, water pump, belt, timing chain etc. Could someone help me out on exactly what parts and areas i need to tune-up?

 

How many miles do you have? New spark plugs will help any car over 60 thousand miles, and the very expensive timing belt water pump valve adjustment isnt due until 105k miles.
If you want the full breakdown look in DIY section for threads on 105 service, or may say 120 service
