I would suggest that you write a mock CAT to figure out your strengths and weak areas. Depending on your score you can figure out when to start preparing. Its possible to score well in CAT by preparing rigorously for 4-5 months if your basics are good.

There are usually two ways, by taking CAT and then WAT/PI. For second one, if you have lived outside India for at least 18 months and are away during CAT examinations, you can apply to IIMA using your GMAT Score. There is separate process for that.

Yes. Maths is very useful for CAT. One of the two papers in CAT checks your quantitative abilities. However majority of questions are from class 9th to 12th maths. Also you should not base your life decisions on requirements of one examination. If you think your time and energy are useful in other subjects than maths, I think you should take that up.
