With JWST being so far out there, how do they know it reached the correct location and made it into stable orbit? What are they measuring/referencing to verify it’s where it needs to be?

They use radio to locate it. Ground stations can precisely locate the origin of its signals in the sky. By timing how long it takes for radio signals to get there and back the distance can be determined, which is all that is required to get its location.
Do that more than once at different times and you can tell its speed.
