Does a DMP share income/debt info with all creditors?

We were on a debt management program from Oct-Jan of this year and I realized I could not make the $2000/mo payments. When they originally negotiated with my creditors, do they disclose all income and debt info that I gave them? Will this hurt my chances of settlement now? We have been slammed with numerous financial hits in the last month and will be sending in $1300 to Uncle Sam in April so we can't get back on our feet without some help. BofA was only willing to lower my payments from $500 to $430/mo which really will not help. Any advice would be appreciated!:confused:
