Yes, you can get admission in JBIMS through MH-CET, but the competition is too tough and for outside Maharashtra candidates, there are only a few seats plus you need to score 99.99 percentile compulsory and then only your chances are there. You can apply for the entrance, prepare well and just bang on.

From these two, ITM (Dombivli) is better.

It depends on you whether you want to add something or not. But assured that nothing extra will be required for your admission in this college other than the entrance exam and your 10th marksheet.
Best of luck.
