This seems like two questions.

You will need a visa to enter the U.S. unless you come from a country subject to the Visa Waiver Program (http://travel.state.gov/visa/temp/without/without_1990.html).  You will not need a visa to 'flagpole' for Canadian immigration purposes.

The Permanent Resident Card is the best proof of being a P.R. in Canada.  You are required to carry a P.R. Card if you travel to Canada by a 'common carrier' (plane, bus, train, boat).  If you travel to Canada by a private car, your passport and COPR will be sufficient (but not ideal).

Yes, you must have a visa to the U.S. unless you are a citizen of a visa waiver country (or Canadian).  Having a P.R. card does not grant you visa free access to the U.S.
