Looks good. A couple pointers to add:

You don't have to remove the stem pinch bolts, just loosen enough to allow the stem to slide on the steerer.

The top cap bolt sets the headset compression: tight enough so there's no play if you squeeze the front brake and rock the bike back and forth, but not so tight that it binds when rotating the fork left to right. I might put the handlebars on during the headset pre-loading (setting compression) to make it easier to test with the front brake.

Use all the spacers, even if it means you have to put some on top of the stem. If you don't have enough spacers then the top cap will hit the top of the steerer making it impossible to set the preload.
