Itr and books of accounts

Hello Friends 

I have salary income of Rs.2,95,000 from salary and I have also earned research consultancy income of Rs.1,65,000 from one customer as an individual consultant FY 2011-12.I have less than Rs.10,000 interest income.These are my total income for whole year.

Both My employer  has deducted applicable taxes for FY 2011-12 and my consultancy customer has deducted TDS at the rate of 10%.

Now I want to know whcih ITR Form should I use for return  filing .

I have not maintained any books of accounts for consultancy income.Will it make any effect ?
