sheriff sale, foreclosre, and junior liens

I live in Minnesota and am currently facing a sheriff sale on my property. I have an 80/20 loan. The initial junior lien was a purchase money loan but several years ago I had to refinance with another 80/20 due to divorce (had to refinance the house solely into my name). I defaulted on the primary loan in April due to unemployment/underemployment (and yes went through all the rigamarole to try and get HAMP which I qualified for but Bank of America kept wrongfully declining me, I even got the MN attorney generals office involved). I am presently current on my 2nd mortgage. I owe 155K on the primary and 25K on the secondary (180K total). The fair market value of my home is somewhere around 130K (yes I know, that sucks the my home has lost 70K of its value since purchase despite home improvements, what sucks more is having paid extra to principal every payment for the last 7 years only to be bent over the proverbial barrel because I lost my job) My questions are many and somewhat complex, so even a referral to a help line (other that the hope hotline who can't help with this issue, I've tried) would be useful
1. What becomes of the second mortgage after sheriff sale? I will have to move and rent and cannot afford to pay rent on a new place and mortgage on house I no longer even own so it will go into default as well. What is their recourse against me? I have conflicting accounts as to the junior lien holders rights pertaining to purchase money loans, non-recourse, and foreclosure by advertisement.
2. In spite of all this mess, I managed to get myself married 2 months ago (family paid for it, and it was a bargain budget wedding, so please withhold the judgements as to why I would get married while losing my house) The house (and mortgages) are in my name, what if any effect/recourse will there be on my husband?
Any (intelligent) help/advise would be greatly appreciated
