Doing LS Swap - I have no idea what I'm doing!

[EagleChief]

Took delivery of the new (to me) setup this past Thursday! I got everything with it, too. All wires, computers, hookups, O2 sensors (and the exhaust pipes they are attached to), gas pedal, front accessories - all of it.

Now, since I have no idea what I'm doing, it's time to figure out what I need to do now.

I still have to get the old crossmember out. It was welded in, so I need to figure out how to get under there and cut it out with my grinder. After that, I'm guessing I can go ahead and get the motor/trans in the truck, right? Then I can go through and wire everything and do the fuel lines/setup? Main reason I'd like to go that route - I borrowed the engine hoist, and my friend is going to need it before long to do work on one of his cars.
