Tier 2 Visa - Document list for Main Applicant and Dependent

Hi Evereyone,

I have job offer from 'A' rated sponsor in UK on Tier 2 (General) visa, have received CoS as well. My sponsor has also provided me with the maintenance letter. My start date is on first week of April-2016. I am an Indian citizen and currently residing in India. I am married for last 5 months. Can I apply for visa for both of us (me and my wife) together?

Do I also need to submit documents like last 12 months payslips, IT returns, bank statements and previous companies offer/relieving letters? Because nowhere in https://www.gov.uk website mentioned the requirement of these.

I also read in the forum that I need to submit wedding photos and invitation card. Is that true?

Please help me which all documents I should be submitting for myself and to my wife as dependent.

Thanks all for your valuable suggestions.
