You'll need a valve adjustment. I wouldn't get an oil pump yet. They usually last 200k or more, and if it went out your oil pressure would drop causing the oil light to come on. (BTW if it ever comes on, turn the engine off ASAP!) I think you've covered everything else besides tranny fluid change which should be done ATLEAST every 30k. The dealer will have a sheet explaining every thing they do at 90k. I wouldn't do any extra because it's really not needed. As long as you follow their intervals, and change the oil every 3k it should last 300k+ miles.
