With the differential, I'd probably go ahead and change it. This seems to be a neglected fluid. When I ask friends (non car nuts), they give me a blank stare so I conclude they aren't even aware.
PS Fluid, easy check and if it's a hint of dark/cloudy, change it. One thing is if there is a tight seal at the inlet, outlet houses to the pump, pulling them off to drain the reservoir may begin fluid migration out of that area. That was my experience and I'll need to install new hoses to avoid excessive PS fluid from getting on the alternator.
Depending on your climate, some of the suspension bushings may be showing their age and have hardened or cracked. If the car feels "tight", no worries. In similar, struts may also be aging possibly a chnage there too.
Then there is the LCD issue which is stickied at the top of the forum. Just an FYI.
Otherwise, anything else, just ask.
