The Lower Intake Manifold (LIM) is under the Upper Intake Manifold (UIM).
Here is the guide for the 1998 from Autozone - the lower intake is slightly different from your car, and the upper intake is quite different, but I hope this gives you an idea. The lower intake manifold is the part that goes down between the heads in the vee of the engine, while the upper part is plastic and sticks up above the heads.
I did both the upper and lower intake manifold gaskets on my van due to a vacuum leak in the upper, stumbling (suspected EGR issues) and a slow coolant leak (less than a quart a month) that I believed to be due to the lower intake manifold gasket. All were fixed by this procedure, and the P0171/P0174 codes went away as well. On a 99+ like what you have, be sure to get new isolator bolts, as these are a common source of problems.
This (also from Autozone's Repair Guide for a 1998) shows the lower manifold.
If it hadn't been raining / I hadn't decided to work out in the nice weather that turned horrid, I could've had it done in a day, easily. For me, the most time-consuming part was carefully cleaning the manifolds and the EGR system, as I was very meticulous.
I hope this helps.
