If I'm correct, Marx always viewed his task as one to criticise the capitalist system and analyse it in terms of the history leading up to it, rather than define how a Communistic society ought to be implemented. Marx is quoted as having said that Communism is an ideal to strive toward rather than one to be implemented directly per se. Fewer people would have to work under a post-capitalist mode of production. I don't know how it's decided who works, but generally those with the appropriate skill would share labour amongst themselves, and people would be trained in the education system to do the jobs required by society. Again, the number of these jobs will be relatively small due to massive automation, which will occur at an increasing pace compared to the current capitalist system (in which too much automation means less profit, because goods are bought back using wages).
