Please help in taking a decision

Dear sir
I have comepleted 1 year in NIT Bhopal Electrical Engineering.
In my 2nd attempt, I got 306 marks in BITSAT 2012.
My interest is in getting BE degree and later try for MBA.
I am more interested in BITS PIlani campus.
I have no much idea on Goa especially with respect to Ranking and other personality development programs.
I think BITS Hyderabad is too young to consider when I compared to NIT Bhopal.
So I need your help in making a decision because the impact is 1 year of my NIT , Bhopal:

1. Does it worthwhile to join BITS PIlani by lossing 1 year.
2. After BE, which is better MSc Tech or MSc dual. I want to go for MBA
3. In Msc dual which is primary/first degree (is it MSc ) or can I say I am as BE and MSc
4. Does Pilani campus have coaching institutes for CAT, GATE and GRE. Are they reputed
5. Does pIlani professors teach GATE coaching and materials etc
6. Does Pilani Hostel rooms are independent from Year 1 ?

Please advise if I can waste 1 year and join Pilani campus.

Thanks&Regards
