i'm bad writing in english but i will explain.
1.- To make objects move, if you mean meshes (like wombat animals) you can't. Because right now FH doesn't have support to mesh animations.
Particles is different, they always have movement due to scripts. To make your own particles you can learn downloading the Ogre demos here:
http://www.ogre3d.org/download/demos and then search for the few particles available in the demos, you can experiment with these particle modifying values.
And you can read the manual for particles here:
http://www.ogre3d.org/docs/manual/manual_34.html2.- Ask to the person who uploaded that wombat meshes, is the better thing you can do.
3.- your map is working correctly. Only i extracted all files and copied them to export folder.
