There are 1,000,000 little parts that are not known to anyone yet (e.g. 10% tanning bed tax??). Here are the main themes:
1) Health insurance will be mandated for purchase by all (circa 2013) or a $700-ish per person per year tax will be imposed
2) Businesses over 50 will have to buy health insurance for all employees (around $2000 per employee penalty) (also circa 2013 I think)
3) No one can be denied coverage (circa 2014??)
4) The ratio of highest to lowest premium will be capped regardless of risk category (2:1 I think)
5) Until 3 happens, States will receive some kind of subsidy to create a high risk pool of people (which is already in place in almost all states, this is not really much of an addition but perhaps federal subsidy makes a difference)
6) All health care plans will be subjected to minimum coverage requirements (the outer bounds of current HSA plans will be clipped a bit by the deductible caps)
7) FSA contributions will be capped at $2500 (this is relatively low compared to today)

States will be required to create risk pools that individuals and small businesses can buy into at relatively low rates compared to today
9) If you are of very low income, the States will be required to carry you under Medicare (unlike today, they may automatically enroll you without you applying - but I can't remember if this made it into the final bill)
10) If you are above very low income, up to around an average income you will receive a direct federal subsidy on buying health insurance
The exact dates and terms of these provisions are not available off the top of my head. Further, there are many many small pieces to this bill that are not even touched on above, and many of which are not even related to health care. However, the above is the gist of the thing, and it will not be fully implemented until 2014 or so.
Hope that helps.
