Using annuities for retirement income

I would like to retire in May 2010. My problem is that I have 2 annuities from different companies, one is SP 500, SOUTH GREATER, AND ANOTHER WITH LAUREL ANNUITIES, ALL COMPBINED ARE ABOUT $100,000 OR $90,000. IF I RETIRE I NEED A LEAST $1000.00 TO $1500.00 A MONTH MORE TO BE COMFORTABLE. I WILL ALREADY BE BRINGING IN $2000 A MONTH FROM A TEACHER RETIREMENT SYSTEM. HOW CAN I GENERATE MONIES FROM MY ANNUITIES. I WILL BE 59 1/2 IN JULY 19, 2010. PLEASE HELP!
