It was not plugged, but did have some build up.

I also will be replacing the crankcase breather, as it is all dark/oily and heavy.

Any other things I should be watching for?

That sensor is done! -- REPLACE IT WITH A NEW ONE!! -- YOUR NOT GOING TO CLEAN IT WITH IT THAT BAD!> The pressure part of the sensor is way up in the head of it, and from the color of it, it has NEVER BEEN REPLACED!>

DO A THOROUGH EGR TUNE-UP ON THE ENGINE AND REPLACE THE RECOMENDED SENSORS, DON'T BE A CHEAP BASt4ARD AND THINK YOU ARE SAVING MONEY BY CLEANING THEM IF THEY ARE THAT OLD! - It will only cost you fuel mileage and more problems.
