In my opinion, understanding Diamat from the get-go is important
I think it's best to start with the history of socialist and political-theoretical ideas like Engels does so one can develop a gradual understanding and see how it fits within the landscape of political ideologies.
Similar to Prolewiki, I would probably do Principles of Communism into Elementary Principles of Philosophy into Socialism: Utopian and Scientific because I think Politzer does a good job of making Diamat extremely easy to grasp.
