Planning to do 75k mile service

[pavanbabut]

Hi all,
I am thinking of doing a 75k mile service on my svx atleast at 80k. Well before that, I need to know what all are recommended to replace for a 75k mile service. I think engine oil is leaking from my cam seals, as I can see oil all over the place between the center of cam belt covers and the engine (underneath the engine) and also valve covers (just to be safe and clean). Also I am having some rough idle problem, its not that worse like engine stopping all of sudden while idling, but the speedometer moves up and down and the car shakes a little.
thanks,
