Abstract confusion - (May/29/2009 )

I have to submit one abstract for poster presentation and would like to consider this for oral presentation. In the abstract I have to add reference as well. Should I put my paper in the reference list which has been publised.
I am presenting the same paper in the conferenec should I site it into the abstract or not.
regards

If your paper is relevant to the work presented in your poster, of course you can cite it.
