Yes the actual name of the Obama program is the Home Affordable Modification Program HAMP or HMP. With the Obama plan your mortgage company would adjust your payment to 31% of your gross income, they can lower your interest down to 2%, extend the term of your loan and look at forbearing some of your principle balance to get you at 31%. Not everyone is approved for the program for example if your PITI (principle, interest, taxes and insurance) is already under 31% of your gross income, or if your mortgage company is not able to lower your payment enough to get you at 31%.

I would reccommend going to the HAMP website, they have an eligibility section, which would tell you, if you qualify and when figuring out your gross income remember that there are 52 weeks in the year if you are paid weekly. So take your weekly gross mulitply by 52 and then divide by 12 to get your monthly gross. And 26 weeks if paid bi-weekly. (sorry everyone seems to just multiply by 2 or 4 for their monthly income)
As far as your credit cards, I would say go ahead and settle with your credit cards. They will most likely run a credit report with any mod, but your mortgage company really wouldnt care if you are paying on credit cards or not. They do look at your DTI (debt to income) when approving a mod, to determine if you can still afford a modified payment. Generally they would still count you as paying on your credit cards if you have paid within the last 90 days.
