Can I do this on Final Cut Express 6 or 7?

Hi all.
I'm considering purchasing Final Cut Express. I will probably be buying Final cut Express 6, as it comes with Soundtrack.
I'm wanting to know weather the following would be possible in Final cut Express:

A shot of a man against a green screen, where the green screen would end up as stars and galaxies in space.
I'd then make a CGI rock floating in space for the man to stand on, using Blender3D.

If I made the whole scene without moving the camera, would I be able to add fake camera movements afterwards? e.g. zoom the camera out from the man?

Also, would I be able to filter footage so it looks like it was filmed on a mobile phone camera?


Thanks allot!
