Mr. Crazy name checking in 
The motor mounts are the same and your transmission will bolt up. The 5.4 uses an 8 bolt crank so you will need to make sure you either have an 8 bolt flywheel or an 8 bolt flex plate.
You will only be able to run stock manifolds or shorty headers and you will need to widen your mid pipe. Personally I would used a tubular K member but I've heard it's not necessary. Plus it helps off-set the extra weight of the larger engine.
I did mine with a Vortech instead of using the lightning Eaton because I just couldn't stand the complete loss of hood clearance. I'm trying to find the picture but there is a member on another forum that has the full lightning setup and the thing is massive.
You run into problems because the Eaton's air inlet is on top of the supercharger opposed to a KB or Whipple which enters from the rear. If I was going to do the swap with a positive displacement blower, I would only us the KB or Whipple because I just couldn't handle having to cut a hole in a 3 1/2" cowled hood.
If you have any more specific questions, feel free to ask.

Crazy with the 5.4L swap craze lately. I just bought an intake from the Australian Falcon Boss 290 for my swap. Searching ebay australia lately has come up with a few, and that is how i got mine. The guy was selling the whole engine but after asking said he would sell just the intake. Shipping was a pretty penny though.

See I could see doing this with a Whipple or KB which both have rear inlets.... that would save you a considerable amount of height. That's what really kills the Eaton setup, is the inlet being on the top.
