Answer:
1. He had promised 3 things. ("Peace, Land, and Bread.") However, he did not keep his promises. He closed the Duma down when it did things he did not like, and the Duma had very little true power in Russia. So no, I would not say that he was successful.
2. He had forged a triumvirate alliance with Lev Kamenev and Grigory Zinoviev in May 1922, against Trotsky, until his death in 1953.
3. He served as the General Secretary of the Central Committee of the Communist Party of the Soviet Union. His 5 year plan was called "пятилетний план, первая пятилетка" (Thats in Russian). But it was a list of economic goals, created by Communist Party General Secretary Joseph Stalin, based on his policy of Socialism in One Country.
4. Ok, I looked this one up. "The term was used by Vladimir Lenin after coming to power, as early as in the decree of 28 November 1917: all leaders of the Constitutional Democratic Party, a party filled with enemies of the people, are hereby to be considered outlaws, and are to be arrested immediately and brought before the revolutionary court."
