Should I declare bankrupcy? What are consequences of judgements?

What are the consequences of this for me? What can I expect to happen? Will I be taken to jail? I have no house or car but have some personal belongings (computer, bicycle, books, etc).

I have very bad credit, and though I am trying to get a loan so I can settle with these two creditors, it is not going well. I have no money to settle with these two creditors.

If they do obtain judgements against me (which is likely), what is the best way to protect myself? Will they take the money I get paid from work? If so, how am I expected to pay for rent and food?

Would it be wise todeclare bankrupcy? If so, can I do it without a lawyer? If not, around how much would a lawyer charge for bankrupcy?

Thanks
