Yes, there are certain similarities. Calvinists believe in what they call the sovereignty of God, which to them means that God is in complete control of all that occurs, including the salvation of any given person. If someone is saved, this means that they were predestined to salvation. Strictly speaking, one can do nothing to initiate the saving event, but must be called of God, whereas even modern Evangelicals think that one has the option of whether or not to believe in Jesus. (It is also true that JWs who claim to be of the anointed class have made an individual decision to serve God, but their being anointed is God's choice and so they are similar in that respect to the Calvinist elect.) So the Calvinist doctrine of the "elect" is similar to the JW 144,000 with the heavenly hope, although Calvinists do not have an earthly hope for others to fall back on. Nor do they claim to know the number of the elect, as they do not take the 144,000 literally - only God knows.
The Calvinist God is apparently more concerned with his own glory than he is in displaying love toward his creatures. While Calvinists do not claim that this involves glorifying a literal name for God - such as Jehovah - it is quite similar to the JW view that God's main purpose is the sanctification and vindication of his own name.
As for any other similarities you have mentioned, I am unaware of them. I hope I have stated the case fairly, and if any Calvinists read these posts they may correct me if I have been mistaken.
