I am sorry, but none of what you have said makes any sense from a Marxist perspective.

1. The presense of Commodity production does not mean the system is Capitalist. To that extent, if you have a 99% publicly owned and centrally planned economy, it must be Capitalist, and once that final 1% is absorbed, it becomes Communist. There is no Socialism by this definition, it's a straight jump from Capitalism to Communism. Even in the PRC, the majority of the economy is Publicly Owned and Centrally Planned. Engels disagrees with your stance:

Question 17 : Will it be possible to abolish private property at one stroke?

Answer : No, no more than the existing productive forces can at one stroke be multiplied to the extent necessary for the creation of a communal society. Hence, the proletarian revolution, which in all probability is approaching, will be able gradually to transform existing society and abolish private property only when the necessary means of production have been created in sufficient quantity.

You kill the Scientific and Dialectical aspects of Marxism and deny the existence of Socialism.

2. This is really 2 points in 1. "Employer" is not a class. Classes are not jobs, but relations to production. Communism will have managers, planners, and so forth to assist with economic production. The other point, on the PRC not using labor vouchers, that's for when China reaches Communism, when they are currently Socialist.

3. This is entirely anti-Marxist. The State is an extension of the class in power. In a fully centrally planned economy with full public ownership, there is no state. The bourgeoisie is focused on competition and accumulation, it isn't a "power dynamic" but a social relation to production. From Engels:

When ultimately it becomes the real representative of the whole of society, it renders itself superfluous. As soon as there is no social class to be held in subjection any longer, as soon as class domination and the struggle for individual existence based on the anarchy of production existing up to now are eliminated together with the collisions and excesses arising from them, there is nothing more to repress, nothing necessitating a special repressive force, a state. The first act in which the state really comes forward as the representative of the whole of society -- the taking possession of the means of production in the name of society -- is at the same time its last independent act as a state. The interference of the state power in social relations becomes superfluous in one sphere after another, and then dies away of itself. The government of persons is replaced by the administration of things and the direction of the processes of production. The state is not "abolished", it withers away. It is by this that one must evaluate the phrase "a free people's state" with respect both to its temporary agitational justification and to its ultimate scientific inadequacy, and it is by this that we must also evaluate the demand of the so-called anarchists that the state should be abolished overnight.

Bolded the most relevant bits. The state ceases to exist when classes cease to exist, because when all property is public there are no classes. However, production remains administrated and directed! I think it's quite obvious from reading the source material that Marx was no Anarchist, nor did he believe that Socialism was devoid of private property, nor could it be. This is a gradual process for Marx, one we call Socialism, as it works towards a fully Publicly Owned and Centrally Planned Economy, Communism. The government does not "extract surplus value" in a profit accumulating manner, but to pay for public services and infrastructure, directly spelled out by Marx in Critique of the Gotha Programme. The State is an extension of the dominant class, and the class which is dominant can be found through real analyzing of the trends and conditions of an economy. In the PRC, those trends are towards uplifiting the working class and continuing to fold Private Property into the Public Sector.
