I'm not a physicist but I know some physicists and can answer your questions...
-What is the daily routine of your job?
Theorists and experimentalists are different, and it also matters if you work in industry or in an academic setting. An experimentalist would be more likely to be actually doing stuff (building, fixing, or fine-tuning physics experiments) while a theorist would be more likely to be writing papers or discussing ideas.
In an academic setting, there would be classes to teach, labs to supervise, office hours, recitations, etc. etc. There would also be travel to give talks at other universities (for either experimentalists or theorists). Various graduate students and postdocs would need to be supervised.
In industry, it would be more of a typical office environment.
-What kind of education is required for that job?
A whole lot. A doctorate and then usually one or two postdoc positions before getting a permanent position.
-What are the entry level and intermediate jobs out there that you would normally have before you work your way up to a physicist?
First you get a bachelor's degree in physics. Then you're a grad student until you get your Ph.D. Then you get a postdoc or two (postdoctoral position, a paid job that is temporary). Then you get a professorship (if you're going into academics) which may or may not lead to tenure. If you're unable to get tenure, you move to another institution or get an industry job or leave the field.
It ain't for the faint of heart.
