apaches ls4

Im a new member,and purchased a 2000 ls 400 last fall. I have 65,000 miles on it and would like to change all the fluids and filters myself,spark plugs included.Im interested in doing this work myself and wanted to know if these forums had any tutorials on this particular model (1998-2000).Also does anyone know where i can find a repair manual,besides the dealer where i would have to wait 2 weeks before i get it in my hands. thank you.
