H1b Visa expired 2015, should i reapply through the lottery system

I had a valid h1B from a period of 01/2011 to 01/2014. However, I have not worked during the period as I had to return back to India. Now, I am considering to go back and for that do I need to go through the entire lottery process. If not what is the approach that I can adopt.

My current employer is ready to bare the cost and apply but the process seems to take in year. Can I reuse the same H1B as it? And also, if I reuse can spouse apply for H4 EAD

Any advise would be much Appreciated !!
