With respect to your other links, the simple answer is yes. Those quotes are routinely repeated all over. However, at no point have i been able to discover any actual reference to where or when Lenin made the alleged statements. It's like the oft quoted statement attributed to Cicero concerning balancing the budget. When you dig, you find nothing but air.
By contrast, if you look up a phrase such as "From each according to his ability to each according to his need." you will quickly find a source citation (it happens to be Karl Marx in his Critique of the Gotha Program). Interestingly, when I visited Moscow in 1964, this statement was in bold type on the wall of my floor but was attributed to Lenin.
