Okay, I just replaced the thermostat and flush and filled it. It overheated while driving it. Does the coolant system need to be burped?

I know it's self purging. While putting the coolant in, it took a long time to fill.

I would purge the cooling system, always needs to be done when work has ben done. Here is a video on how to purge the cooling system... https://www.youtube.com/watch?v=xeTgmdRkQtY

The only thing with that video is put the radiator cap back on before you shut the engine off.

Should the car be raised up?

Sorry, had to take the dog for a walk, but yes, having the front end up on an incline or raised up certainly helps.
