Yep, you're right in all of this, although there is some disagreement and ambiguity as to how classically marxian, noble and world-economy-oriented Lenin was, given that he was a right-communist and did state, back off, and eventually renew the approach that would later be termed Leninism: capture of the state apparatus and representation of the proletariat by the central bureaucracy, instead of ground-up fomenting of economic organization and productivity. You can go back and forth on whether the Leninist approach and the NEP era was just a temporary transitional state to fund the European revolution (this was certainly the position of Trotsky) or whether Lenin was just an opportunist rolling with the punches.
Yeesh, I wouldn't go that far. Do tell.
