Hi Arwinder,
You cannot study in two countries simultaneously. You can do your B.Com abroad through online or distance and do your CA here. Check here for college list

There is no such boundation to take maths in class 12th to pursue CA. You just need to appear for CPT for the same.

You can appear for IPCC after registration and then you have to complete 3-year articleship and then the final year.

I think, CA would be a better option.

As per eligibility guidelines for pursuing MBA one needs to be a graduate or in absence of graduation have a professional qualification like CA/CS/ICWA. So, if your case you can seek admission based on your professional qualification as a CA.
