Did you hire a lawyer to just prepare the paperwork or, to represent you in bk? If it was just to do the paperwork, I don't know why you think he should have advised you on anything. Not trying to pick on you but, I hope everyone reading this understands why it is so important to be represented by counsel in bk proceedings. What you don't know can surely hurt.
None of the options are that great. You can cancel the petion and refile in 180 days but, you open yourself up to collection activity. Can you avoid a lawsuit and a courtdate and a the resulting wage garnishment for 6 months? A settlement has problems as well. The difference between the amount owed and the amount settled will generate a 1099C if the difference is over $600. The 1099C wil reflect taxable income.
I personally think it is time to hire a lawyer for the entire process.
