control arm bushings (believe supra only has lower bushings), end links (for sway bar) and sway bar bushings (these mount to the unibody and are the actual "stiffening" point) and last but not least, strut mount bushings/bearings. unless you have the electronic suspension, i believe.
as far as my steering stops go, no, i cannot grease mine. they are a replacable part.
here are some from ebay, they are the more expensive ones ive seen.
and i do believe that the resevoir you are seeing is the washer fluid resevoir, as btwilson said.
