H1B Visa under cap exempt approved - Interview

[need_info]

Hi,

I had a H1B Visa (filed by Employer A) approved in 2007 cap which I did not use at all and it got expired.
Fortunately now Employer B has filed cap exempt and got the Petition approved with 3 years validity (2013 - 2016).

My Visa interview is scheduled in the next 10 days and following are my questions?

1) In the Visa Interview, can I face a question by Visa Officer about not using my previous H1B Visa
2) If Yes, Can I say that it was because of recession / bad job market in US that I did not travel (or) what could be a valid answer?
3) The current Employer B has given me an in house project. I do not have a client letter. I am worried if "in house project" causes problem for my Visa. I am in an impression that client letter has more weightage than an in house project. Please clarify.
4) Can I go for the Visa Interview along with my Family (or) wait for 2-3 months and let them attend the Visa interview.
5) My kids had their B1/B2 Visa stamping done just 2 weeks back. Does this influence, if we go for H1/H4 B Visa interview now?

Thanks

1) yes, u can face
2) yes u can tell that that at that time no requirement was there, so employer did not sent.
3) yes u can go, but better u can stamped ur earlier...
4) no influence

Just tell me one thing how much time it takes to approve ur new petition against ur old expired petition ? (cap exempt)
