Will the unemployed be required to buy health insurance, too?

The New York Times' "Prescriptions" blog describes some of the rules around this. (The short answer is that there are exemptions built into the legislation for people who cannot afford it.) From the blog:

In general, everyone is required to have insurance starting in 2014, even people who are unemployed. But you’ll be exempt from the requirement if your income is below the tax-filing threshold (in 2009, that amount was $9,350 for singles under age 65), or if buying even the lowest cost plan on the new health insurance exchanges, set to open that year, would exceed 8 percent of your income.

The post also includes details about potential options for Medicaid coverage or subsidies on the exchanges.
