The spoiler is fairly easy. there is the four bolts in the spoiler and all Focus' have the plugs and spot on the inside of the trunk where you drill. Just measure the center of these holes and drill from the inside (so you get it as true as possible) and the place on and fasten down.....that should be the point where BOB is your uncle.

Your looking at about 100-200 for a spoiler from the junkers (at least thats the quotes I got) and some places wont sell just the spoiler, trunk has to go with it (cause there would be holes when you take it off)

I put a spoiler from a 95 bonniville on my 01 sedan and it looks pretty darn good actually.
