The good news with Kalecki is that he's extremely terse and you can get all his widely-cited writing on capitalism (he also wrote a lot about socialist planning) in a single 197-page volume, 'Selected Essays on the Dynamics of the Capitalist Economy, 1933-1970', Cambridge University Press, 1971. What might be bad news is that he's so terse partly because he likes his mathematical presentation. That said, the maths are not very difficult by today's standards.
There's a great, readable intro by Malcolm Sawyer which is one-and-a-half times the size of the 'Selected Essays': 'The Economics of Michal Kalecki', Macmillan, 1985.
