The UJ grease in later cars is almost like Swarfega to look at, a sort of green slime. It's been said already. Don't overdo the propshaft U/Js. It can lift the seals and let condensation inside. It will also spray a line of grease around the inside of the tunnel. After 700 miles, an oil & filter change, and a kingpin grease plus a visual check underneath to make sure nothing is working loose and that should be it.
As above, but if its been 3 yrs I'd also whip the plugs out and put em back while you still can..
