Do I need to send the first payment with voucher by mail or are they going to direct debit as I requested with the and do I need to include the agreement form ?

If you are referring to the first payment under an installment agreement with IRS that you requested, and you have not heard from IRS, then yes mail the first payment.  You don't need to send a copy of the Installment Agreement request, but be sure to indicate what tax year you are paying for and include your social security number.
