Go for Nikon 5100. Trust me if you are serious about your hobby you will be very quickly outgrowing the basic 3100 body and then u will start itching to upgrade the body
The middle range 5100 is where u will take some time to be an expert at.
Now lens thing .... start with kit lens !!!
Once u adopt the hobby, u will develop a style of photography and then u can decide what is your favourite shooting routine. Choose upgrade lens accordingly. I guess right now u don't know what u would be shooting but once u get into it, u will definitely be looking for one specific area more than other.
