Dispute a loan mod w/indy mac bank?

my place i own in seattle is in foreclosure. indy mac bank approved me for a loan mod. it's still too high (1,450). was hoping for 1200 or so (hoa fees are $300). i heard you can get a lawyer and dispute it? the auction/foreclosure is set for march. the new payment is only $100 less. i'm hoping i get get the bank to redo the loan mod? what kind of lawyer helps with this? i'm staying with a friend in bellevue while i sort this out. freaking out about this because i'm confused if i should let the bank foreclose on the condo, or do a short sell (am i responsible for the tax if i foreclose? what about shortsell?) the value of the condo is 129K and my loan is 189K. is this worth fighting for? it could take over 5 years for the value to rise enough to where i could sell and at least break even. if i let it go, then what? become a s bag renter with a foreclosure? i already had to file bk this year. ughhhh.
