Is the Canon 50mm f/1.8 lens comparable with the Canon 450D?

I read in a comment that the 450D has no microAF and that this lens was front focusing.

I’m not exactly sure what this means - but does this make this lens unusable/difficult with the 450D?

Pay no attention to what you read, any ef 50mm f1.8 model will work just fine for you. That said 50mm on a Rebel is a tough FL to live with unless you have a specific use for it. It always seems to be either too long to too short for the shot.
