I'm Confused.

I realize nobody reads my blogs (lol), but on the off chance that someone starts now:

Could somebody clarify for me whether the Health Care bill that passed the House of Representatives last night is now going to be a law, or whether it still needs to pass the senate?

The way I understand it so far, and the way that CNN seems to be pushing it as, is that the core of the bill is going to be sent to President Obama soon to be made into law, and the changes to the senate version are going to the senate for a vote. So then do the changes take effect when Obama signs the bill into law or when the senate passes the bill?

If someone could clarify this for me, that'd be awesome.
