From experience, the only skid plate you will absolutely need is...
#8-97049-784-0 trans protector $60.00
#8-97104-788-0 bolts $0.56ea
get 4 bolts.
It replaces that flimsy tin crap that's bolted to the crossmember now.
If you really really really want the other skid plates they are...
8-97018-375-2 Heat Protector $87.71
8-97036-238-1 Frame Protector $ $39.08
I think these 2 are a waste of money. The heat protector is the skid plate from the older Trooper which protects some exhaust piping that we do not have. This is also the one that hangs excessively low, I took it off.
I am still using the frame protector only because I am too lazy to get back under my VX and take it off It does seem to cover about half of the torsion bar. But really, we don't need it.
Keep in mind too that these last 2 were on back order for about 2 months too.
