Springs don't wear out except in one way: the rears on c900s can "take a set" and sag. The spring rate does not change, even on a sagging spring. Therefore, if your car is properly level (see your Bentley for the ride height spec), installing new springs will do nothing unless you've ordered some stiffer, shorter "performance" springs.
Your new shocks will already have bushings installed on them; the list you typed implies that you are getting additional bushings.
Not sure what "spring supports" are, but if they're the rubber pieces that fit on the end of each spring, then they, too, do not need replacing unless, somehow, they have come apart. (I have never seen this, having looked at many, many 900s, and can't conceive of how it might occur.)
As for the a-arm reinforcement posted by tibbidoh, this is an unnecessary modification for a street-driven car. It is cheaper and easier to clean the a-arms and periodically inspect them for cracks (say, when you change the oil); they always fail at the base of the arm, near or at the weld to the round steel portion of the arm. If you are really concerned, or find a crack, then replace both left & right arms with inexpensive ScanTech arms (one of the few things they sell that aren't junk, IME).
Finally, if you really want to refresh the suspension, check the rubber bumpstop cones at the front springs. If the car has been driven aggressively at some point, there's a good chance that the bottom "bulb" will be cracked (or gone altogether). The super-anal Saaber will replace these, but it's a PITA and I doubt they're even available now, except via a junkyard. Then again, you won't be able to tell the difference once you've done it. You will know as you drive down the road, though, that your lower bumpstop bulbs are intact...
