Some people tend to go overboard on the 60k stuff. I've had 9 of these cars over 10 years so let me impart this advice: If you have oil in the plug wells and no other problems, do just the "top 60k" and don't worry about the rest. Top 60k includes new plugs and plug wires, valve cover gaskets and plug well seals. That's it.
The valve lash is also part of a traditional top 60k, but you need some specialized tools for the job. If you want, you can check the valve lash with a feeler gauge while the cam covers are off, but honesty, at 84,000 miles I wouldn't be the least bit concerned about the lash. Most SHOs never get such an adjustment in 200,000 miles and still run fine.
While the intake is off the car, it's also advisable to get it all nice and cleaned out inside. I prefer about 3 cans of Berrymans B-12 chemtool, just spray it into the snakes of the intake while its off the car and let it swish around for a minute or so.
The timing belt on the automatic isn't due for a change until 100,000 miles, so if you're only at 84k, don't worry about it! Aside from that, this is a non-interference engine, so should the belt break, it won't hurt anything but the belt. The timing belt/water pump/CPS stuff that makes up the "side 60k" is a completely different section--and much harder to do IMO--than a top 60k. The only thing on that list with a definite lifespan is the timing belt, and you still have a ways to go on that. As for the water pump, is it leaking? If not, don't worry about it. Is the car stalling? If not, then don't worry about the CPS.
And whatever you do, don't let the rod bearing police scare you. You do NOT need to change rod bearings at 84k, and I'm not sure I'd even worry about them at 184k unless I was getting a low oil pressure light at idle or some tapping down low. They won't tell you this, but most of the guys who spun bearings are either a.) quite modded, or b.) out racing every other day. Do regular oil changes, don't use some super lightweight synthetic (I can't recommend Castrol GTX 10w30 enough), and make sure your oil level stays high, and you shouldn't have to worry about rod bearings for at least another 100,000 miles.
Never heard of 02 sensors being part of a 60k, or "just good practice" to change. :laugh_ti: They're easy to change, and when they're going bad you'll get a check engine light. If you don't have a check engine light, then don't worry about it, unless you want to spend $100 for no good reason.
Bottom line--these cars aren't as maintenance heavy as some people make them out to be. If it's running and driving fine but has some oil in the plug wells, just do the plugs, wires, and your valve cover/plug well gaskets. The oil will shorten the life of the wires, and the plugs/wires have a recommended lifespan of 60,000 miles anyway.
