A couple of DEP questions?

I am heading off to MEPS on Monday, and I will be put into the DEP program. Right now I'm 6'0 and weigh 196lbs. I know that the cut off is 202lbs, so I think I should be fine there. After I enter DEP do I have to remain under the 202lbs? Not that I'm planning on gaining weight, the exact opposite actually. My goal is 185lbs by bootcamp. And also I work and support my family, these mandatory meetings with the DEP commander (or whatever), what happens if I can't make it? It's not like my family can afford for me to skip work.
