Distance won't be a good idea in my opinion. Some things require practical knowledge and exposure and you should go through it to achieve the perfection. This will also help you in your future jobs when you will gain more skills. So, rather go for regular.

According to the criteria that you asked for, IT at Techno India Saltlake would be much profitable and better than the other option.

Yes, according to your category you have good chances to get admission here. Good luck.

Unique academy is good for MPSC preparation, if you want, you can join.

No, it do not accept JEE Marks, and your MHT CET rank is too high to get mechanical. Can you tell me your JEE percentile?
