Begining process for navy DEP?

i contacted my recruiter today and told him i wanted to begin the process of the delayed entry program...i told him i would have to wait a little while because i have to wait for my system to clear out (pot)...he basically told me we would wait another month before i go to MEPS for my drug test and physical...i already took my ASVAB in high school and I'm supposed to begin paper work on Thursday morning... what kind of paper work will i see and will i be obligated to sign or would i have to wait until my physical was over with (mind you i was told to bring my SS card and birth certificate)
