Based on the information you provided above, it looks like you live in New Jersey. Your health insurance options will be based on the health insurance exchange set up by the state of New Jersey. Your ability to qualify for subsidies for health insurance premiums will be based on the amount of income you reported on your 2012 tax return. Currently, the rules for the health insurance exchange in New Jersey are up in the air, because the state legislature has passed the bill but Governor Christie won't decide whether to sign the bill until after November 6. According to the announced plans for the New Jersey health exchange, Medicaid should cover an individual or family with income up to 200% of the federal poverty limit and subsidized individuals or families with incomes up to 399% (or nearly 4 times) the federal poverty limit. The federal poverty limit is based on the size of your family, but for an individual it is $14,440 up to $21,660 for a family of four.
The 9.5% of income threshold is an example amount that a family of four making $88,000 in income would pay for health insurance. Unless you earn over $200,000 per year, your premium will be based on age, number of people covered, health status, and other factors; but not based on income. If you earn more than $200,000 per year (or $250,000 per couple), then your medicare payroll taxes
will increase from 1.45% to 2.45%. But that is separate from the amount you will pay for medical insurance.
Based on the current New Jersey health insurance exchange plan, the maximum you would pay would depend on the plan. You can go to this web address and get a list of all insurance plans in the New Jersey exchange and the premiums for each plan based on your number of family members, ages, and health. It's an eight page PDF file, but it will give you the plans and the premiums. New Jersey premiums

There is also a health exchange program called "SHOP" that is designed for small businesses. I can't find much information about it and I think that it was part of the business mandate that was delayed until 2014. You might want to keep your eyes open for any information about that exchange, because you may be able to get a better deal with insurance through your small business (self-employed) than you can as an individual.
I hope this answers all of your current questions. Again, though, I warn you that all of this stuff is changing daily, so be aware that the numbers may change between now and the time that you sign up with the New Jersey health insurance exchange. Please let me know if I can provide any more information for you.
