SOURCE: Shaking at highway speeds.
As for your shaking at highway speeds, providing your tires have been balanced properly, it's probably a u-joint. If you let off the gas when it's vibrating, and the vibration quits immediatly, it's a u-joint. If it doesn't, it's a tire or wheel.
The squeak is probably a shock, but that would be a guess.

I just changed the brake pads and rotors on my father's 2001 Trooper that he recently purchased because they were shaking just like your were. He bought it from a mechanic shop and they had put new pads on it but it needed new rotors as well. If there is noticable groving on the rotors and new pads are installed it can create shaking, sometimes severe, when the brakes are applied. It sounds like this is what has happened with your vehicle as well. That being said, I don't consider it a huge safety issue to drive it until you get it fixed, just know that your braking will not be optimal and that it will take you longer to stop than if the brakes were working properly. All that being said, get them fixed ASAP so you don't have to worry about it. Who wants to mess with safety right? Good luck, hope this helps!
