H1B approved but delayed by NVC

I am from india. My employer had filed H1B on my behalf last year(August 2014) and it was approved in the end of the November 2014.

As H1B visa was not subject to regular cap at that time but recently on April 28th 2015(regular cap), NVC asks my employer to submit H1B fees. But from that time to until now, my employer haven't heard from NVC.

So i would like to ask few things from respected members that:

a) When NVC is going to process the remaining part of the case by issuing DS-160 form.

b) As we are in 10th month. So, Will it take more time to schedule an interview.

c) Am i able to start work from 1st October, 2015.
