The Marshall Plan was more economic, as it sought to give aid to all of Europe (although it was refused by Stalin for Eastern Europe). It simply wanted to promote economic reconstruction in European countries so that Europe could be back on its feet. This move showed America's desire to help out devastated nations and the rise of the US as a major world power.
The Truman Doctrine was more political. It imposed the policy of containment, which aimed to give economic and military aid to countries being threatened by Communism. It wanted to "contain" Communism so that it didn't spread. At that time, it was helping Turkey and Greece.
