Teacher

Yes there are. You can do B.Ed. TET CTET and others.

No.M.A and M.Ed are two different courses.At first complete Your B.Ed degree without which you can't apply on teaching jobs. After completing B.Ed you can complete Your M.A or M.Ed degree. According to my view there is no need of M.Ed degree to get a teaching job but M.A is important.it has an academic background.

You can apply other state or some private colleges who are also recommended by UGC and NCTE rules.

You are advised to do B.Ed after B.Com to fulfill your dream of becoming a teacher.

Yes it is very much possible.As now you can apply for the same in distance mode from both or opt to do regular b.ed with distance m.com

Now these days B.Ed is must to get teaching jobs but you can apply other government jobs like income tax officer,tax consultant officer, etc high quality post with out B.Ed.

As it is not a regular job, it depends on the requirement they feel for the subject. If they can't find anybody else, they will pay you more. Or else, they pay less.

There are so many universities or group. You can find out about their placement, history, salary, past year results and other information. Talk to some expert and then decide.
