Different incomes - what itr form should we use to e-file?

Dear friends,

Both my wife and I spent the last year with income from two sources.  Each of use got paid against our PAN's working as individual consultants/ trainers.  TDS was deducted (against our PANs) in each case of payment.

Late in the financial year I started a sole proprietorship with my PAN.  Under this source we earned very little (<1.2 lakh) in the financial year.

Question:

1) Do we both file ITR 1's?

2) Do we both file ITR 4's?

3) Or do we each file something different? If so, what does she file, and what form do I file?

Your guidance is greatly appreciated.  Thank you!
