Congratulations! Put some miles on it!

This is also known as the "intensive wash system". It is a second 
windshield wash system, sharing only the check valves (inside the back edge 
of the hood - they sometimes stick) and nozzles with the standard system. 
The system is designed to apply a measured quantity of the special Porsche 
intensive wash fluid (P/N 928.628.931.00, $20.00 for about a liter). This 
fluid quickly and effectively removes road film and silicone from the 
windshield. It is PFM on a rainy night with heavy traffic. The fluid 
usually evaporates before it is used up - plugging the vent hole (tape, 
RTV) helps prevent this. Most 928 owners don't bother with the system, 
perhaps because many of them don't enjoy driving in conditions where it is 
useful.

The hatch shocks help lift the hatch, and should reliably hold it up, but 
you have to lift the hatch. Same with the hood.  Hood shocks (P/N 
928.511.139.03) are $22.50 each for Genuine Porsche, or $9.99 each for the 
essentially identical OEM unit that everyone buys.  Hatch shocks (P/N 
928.512.331.05) are the same price. Note that these are NOT the same. If 
you put hood shocks on the hatch, they won't hold it up, and if you put 
hatch shocks on the hood, you will bend the hood trying to close it!

The mirror glass just snaps out, and can be removed with reasonable caution.

>4. Should the door check straps hold the door open? Mine don't!

This is a common problem with high mileage. Replacing the door checks (P/N 
928.537.033.04,  $23.01 each) requires removing the door trim panel. 
Instructions are on the Owners Club web site. There are several WYAITs 
(While You Are In There) for this job, such as checking and lubing all of 
the window and latch mechanisms, checking the felt window supports, etc.
