Pulling an engine really isnt that difficult. I did a few at my previous job, and its really just time consuming. Provided you have the correct tools and the patience, its really not too bad.
For a quick summary, things you will need to do:
Disconnect harnesses for all accessories (A/C, P/S, Alternator). I do remember having to pull either the P/S or A/C compressor/pump before, but I do not remember which. May be both. Also need to disconnect things such as battery cables, and connectors for fuel injectors and COP's, or disconnect the wires for a coil pack/wire setup.
Disconnect fuel lines from rails, coolant hoses.
Transmission bellhousing needs to be unbolted from the block, or the transmission can be removed completely. You can do this for clearance or you may have to do it, I'm not sure about the LT's. Remove the starter. Unbolt the engine mounts, and remove the midpipe.
That is pretty much everything if I remember right. It's really not too difficult, just sometimes things can be hard to get to. Worst engine I pulled was a 5.4 out of a navigator. The intake sits like 3/4 the way under the cowl, and it has to be removed for clearance to pull the engine from up top.
