Cams from a Series II or III will not work. The valve lobe order is different.
And you're not a pain yet. I've commited about the worst cardinal sin there is, Gen 3 M62 and TB, 92 MAF, 2.25" pulley, and no adjustment to the fuel or MAF signal. And noone ever called me a pain. I'm lucky my engine made it another 90k miles.

Boost is relative. Depends on alot of factors. I suggest you add an aftermarket boost gauge. Instructions are in Techinfo. You can install it in one of your round dash/door vents.
How on earth did you find a Gen1 supercharger on a 95 L67? I've never even SEEN a Gen1 personally. You should have a Gen3 from the factory, and if it is, it can be assumed, as all 94/95 L67'* got the Gen3 M62.
I mentioned custom grind for the specific reason that you won't find a DOMESTIC cam for your car without going to Crow.

Since this is about Performance, let'* look at your sig:
You have a Gen3 Eaton M62 just like all 94/95 L67'* unless someone did something freaky to your car.
Is your intake truly a 'cold air' intake? Let'* look at your design and heat shield.
18" wheels are the wrong thing for a car you want performance out of.
No cat? Not only is that illegal, it'* also costing you low-end torque. Put a hi-flow cat in.
Custom headers? That'* going to cost you dearly, and probably won't gain you much. Our Series 1 manifolds are a really good free-flowing design.
95 riviera gen1 SC 2.55" pulley cold air intake, 18" wheels with nitto NT555 tires, flowmasters with no resinator or cat.
Future mods: camshaft,ported heads/intake/SC, 2.3" pulley,pcm, custome headers with hi-flow cat

Unless the total height of the tires are taller, its not going to change anything.
unless you get really heavy wheel.

1. 18" wheels are typically heavier than 16'*. This hurts you in accelleration and braking.
2. 18" wheels reduce the sidewall height which is typically bad for cornering. A common misconception is that shorter sidewalls are better for handling. This comes from the import tuner market. It is not true.

If smaller side walls are so bad for corners.. go look at every Over seas High end performance car.. all have 18" + wheels and very little side wall...
*edit*
i am not a fan of 18+ size wheel because i dont like the ride and look of Small side walls. i dont want to feel a tiny rock if it hit it lol
