2000 C5 Corvette Engine Mounts
Aloha
I have a C5 with159,000 Miles and I am getting some Stranges squeaking noises under the car. I am thinking the engine mounts could be shot, but how do I confirm this gues

The quickest not entirely conclusive test requires two people: driver and observer. Get in a car. Preferably a warm engine. Pop the hood. Have one person watch (off to the side) as you put the car in neutral, parking brake on. Stab the throttle. Let it go. Stab the throttle. How much does the engine move?
If it rocks a little bit, no problem. I'm not sure if there's a spec on "how much rocking is okay as I go from 800 RPM to 4500 RPM suddenly" but... if it moves like a half inch or so, it's probably fine. If it jumps up and scares you, then it's not fine.
Honestly these engine mounts are actually pretty long-lived. The problem of course is that they are 22 years old and there are no stock replacements. You can go to AMT and get their captive-rubber mounts, which are probably the most comfortable aftermarket mounts, but I am guessing that this is just throwing parts at the problem.
So let's talk about your squeaks. When do you get squeaks? What conditions? What is the car doing? What are you doing? What's the road like?
