And is this alu shim too short, surely it needs to be longer than the steerer tube to be able to push down to compress bearings?
No, the compression load should go through the stem, not the shim. I'd still want the shim to be longer than the steerer clamp of the stem, but with a spacer under the top cap (or a cap with integrated spacer) to make sure the compression loads bypass the shim.
The washer that looks spare is a bit of a mystery; it looks like it should be a stop for the compression bolt, suggesting that the expander is designed to be set in the bare steerer using the spare washer, then the bolt comes out leaving the expander in place ready to accept the bolt on final assembly.
