Moving to Miami with family

Hi Everyone,

I am about to move in to Miami from Bangalore, India with my family by the end of this year. I am quite nervous about this move and would really appreciate some informations from fellow expats already living there. My main worry is about the below mentioned topics:
-Where and how much does a decent Protected content cost/ month?
-Will it be advised to travel with our household stuff or is it better to buy it all there or rent a furnished place?
-I can't drive as I am quite spoiled in India with private chauffeurs, so how convenient are public transports while travelling with a toddler?
-How easy/ difficult it is to get a domestic help/nanny? and how much does that cost?

Thanks in advance for your help.

Cheers,
Kunj
