bare minimum need to start hemi 5.7 out of car?

I am waiting to get the the auto hotwire kit, computer and wire harness for the hemi 5.7.
Question is, what else will i need after i get this, to make the engine run. I wanna test it out of the car first.
I have a water pump on the engine (don't plan on running it long, just enough to make sure it fires).
What about fuel?
I know im gonna need to get a starter for it to.
not gonna hook the tranny up yet.

so just wire harness, computer, will a 5 gallon gas can and a pump work?, starter and battery?
