Here's the intake RnR from the shop manual.
There is no need to disconnect the fuel line (step 3), and when you pull the fuel rails (step 29) go gently and make sure the injectors stay in the rail (and that the fuel pressure has been relieved¹)--if this is done there will be practically no fuel spillage.
Here's the mess I found when I opened it up:
and almost ready to go back together, before I cleaned up the valley:

¹ - Here's the procedure for relieving the fuel pressure if you have a Schrader valve of the fuel rail, and if not. The "if not" procedure does not require any drain hose and is less messy.

Its funny the same cylinder intake runners are stained with oil with your engine as mine was. The middle two ports on my passenger side intake runner on the block were totally black with oil like yours too(84k miles). With the other ports being partially oil stained as well.
Just so you know. With Windows 7, the most recent version of firefox, and most recent version adobe that "if not" link came up as a gibberish language instead of english. I do not have a schrader valve. When I went to dry my fuel system up for my kenne bell install I just yanked the fuse for the fuel pump and cranked the engine three times. She actually fired right up on the first crank about 10 mins after pulling the fuse but died quick. I was surprised.

I have no experience with Windows 7, probably never will as I am in the process of moving over to Linux.

I've seen the fuel pressure hold at 25 to 30psi for 30 to 45 minutes after shutdown, sometimes even longer.

Some other questions right off the bat:
1) It says "Disconnect fuel line" ... does this require a special tool? I have some plastic ones from when I took the LT1 intake off, but I don't know if they're universal.
2) Does any of this require the car be on ramps or jackstands or can it all be done from the top? The Chilton's said get down under the car and remove the EGR or something. I don't understand why or if that's accurate.

Re: fuel pressure relief;
If you left the car sit overnight there will be little to no remaining pressure. That's what I did, so there was no need to go through the process at all.
If the system is pressurised, and with out having a drain hose that fits the Schrader valve, I would use the "no valve" process. That said, in a pinch, I have put a wad of paper towels (or better yet a toddler size Pampers) around the valve and pushed the plunger with a small screwdriver--only 2 or 3 ounces of fuel will come out, but it can come out with a vengeance with 40psi behind it...
