Which 4L60E do i need?
2000 will work. I have a 2000 4L60e out of a 2000 Camaro. Works on my 2005 LS2, and also worked on my 2002 5.3. There are two different styles of converter though, so make sure you get the right one. If you have the "truck" motor, be sure you don't buy a "car" converter. I guess you could swap flywheels if necessary though.
Also, make sure the 4L60e is is the TWO PIECE trans, not the single piece bellhousing.
This is correct:
This is the older style, and NOT correct:

Notice that the incorrect one has a smooth, one piece bellhousing similar to the old TH350, etc.
As long as your harness plugs into it, it should work fine. Pretty much all the harnesses in that year range will plug right into any transmission in that year range. When you have your computer flashed to remove the VATS, emissions, etc, tell the tuner what trans you have. $300 is a steal if it is a functioning transmission. Go buy it before someone else grabs it.

What is different about the harness connector that prevents it from being plugged in?

Find the plug on the harness of your 5.3 and make sure you have a corresponding plug that looks like it will fit that plug on the trans. Don't quote me on it but I THINK I remember the plug on the harness is black with some white on it. Either way, you'll know it when you see it.
