I've bought a accident damaged crossfire and I need some help please getting it back on the road... (this will be my 2nd crossfire)

These are the parts I think I need but I'm not a mechanic so any advice would be appreciated...

A Front bumper
Passenger side headlight
Bonnet
Crossmember,
Slam Panel

If you have any of these or know where I can get them please let me know.

Now that long bar going accross the front (thats the crossmember right?) its a bit bent here and there, would I be able to get that straightened out or would I need a new one? and at what cost?
What is a slam panel and do you think my car needs it replacing?
I have 2 spaners showing on the dash, that's a major service isn't it? (could someone please tell me what that involves)
The spoiler is stuck in the up position at the moment I tried to retract it via the button on the dash but the light is flashing and nothing happens... is this just a fuse or is that broke as well do you think?

I appreciate it's a bit hard to diagnose by those crappy photo's i'll try and take some decent pictures and post... the problem is that I cant take it to the body shop yet as I've not located any parts. I am based in UK but i'd consider buying from US if price is right.

Thanks guys....
