One gasket is enough......I think 
On Jerry's page you have the Oil Pan Gasket Installation Guide, Oil Pan Gasket for 90', Oil Pump Suction Pipe "O" Ring.
Jerry's Oil Pan Gasket and Associated
Typically.......6 mm bolts go 89 in-lbs (three in front of Oil Pan)
Typically.......8 mm bolts go 19 ft-lbs (fourteen in rear of Oil Pan)
Clean ALL Oil Pan Bolt Holes with cue tip and gas or something similar. Use Blue Loctite (242) on ALL Oil Pan Bolts. As you already know, I use thin coat of Permatex on both sides of the oil pan gasket.
The TRICK is balancing that "O" ring in place while keeping the gasket in place at the same time you start and snug up one 8mm bolt on each side of the oil pan. After that.....you are home free 
Here are the 8mm oil pan bolts (ten) except those two on each side which are studs that hold the exhaust shields. And except the three front 6 mm bolts.
Jerry's oil pan bolts
You need Four
Heat Shield Oil Pan Studs/Bolts
You need Four
Heat Shield Nuts
For your 90' you need Three
Oil Pan Front Three 6 mm Bolts

On a 91' You would have seen a Low Oil Level Indicator on your readout above the radio when you first start the engine.
The Oil Level Sensor was not used on a 90' unfortunately for you.
I am still looking for an LT5 Oil Level Sensor as
Jerry does not stock those as far as I can tell
