If anyone could help I would appreciate it!

I don’t see anything wrong, your model is very low res so don’t expect it to look perfectly smooth even with smooth shading.
It’s fine. Object scale is unapplied and non-uniform. Object mode, ctrl+A -> scale to apply, should prevent later problems with tools and modifiers as well.
Maybe it´s to low-res? Hit Ctrl + 2 and render it again, I guess that helps.
