I'm an especially big fan of #1, 2, 4 and 5:
Tax fairnessRead the full text of "Not Obamacare, but Patientcare" for more details.
Insurance portability
Health savings accounts
End government monopolies
(As a side note, ultimately I believe programs like Medicare, Medicare Advantage, and Medicaid should be fully privatized. The government's job is to protect individual rights and freedoms, not provide entitlement programs. But these programs cannot and should not eliminated overnight. And there's ample room for debate on the precise timing/method for such privatization.)
