Itr filing for salary + stocks + online earnings

Hi All,

I have a few doubts regarding ITR filing. Could anyone please help me out to clear my doubts.

1. What kind of ITR needs to be filed for Salary + Stocks + Online Earnings (blogs)?
2. For Stocks, we do get Profit and Loss statements from the broker but is it necessary to list each and every stock name and profit margin for each?
3. What is the category to declare online income from advertisements? Can we deduct internet charges and other things from earnings? 
    

This is a great forum.

Thanks.
