The stuff I've thought of, below. Looking for the collective wisdom about anything else that should/could be done:

Oil/filter
Fuel filter
Air filter
Coolant flush & fill
New thermostat
Trans fluid flush & filter change
New plugs
Brake pads & rotors (replace front, measure rear)
Brake fluid flush
New serpentine belt
New tires (not really needed except for the one that picked up a 1/2" diameter bolt yesterday)
Alignment

Thinking about, and would really appreciate input:
New shocks
Timing chain (anything to check/adjust?)

Finally, I haven't had any luck finding any service manuals (MB/Haynes/other) except for those iffy looking $80 CD jobs on eBay. Any pointers?
