Blob of text that link is 

Make a copy of a ships entity and add it to the manifest. Tell the new ship entity to use our new ship mesh. We will take it one step at a time from there.

The shield is fairly easy. If you have 3ds max and XSI, import an existing shield mesh to a new scene. Import your ship model to the new scene. Resize the shield for your ship. Delete the ship from the scene and export. Give me a bit and I will upload a XSI scene with a shield in it.

Dude, that link is not pictures or a proper link to them.   I uploaded "a picture" of what I get from your link.

So I can tell from that blob of text you have the model in-game or is it? No point in helping you with buttons or shields if your ship is not in the game yet. I will continue when I can see a real picture in this thread (no more links).
