Your distinction about eternity being “without time” is interesting, however perhaps not supportable. Only God is timeless.

"When [the Lamb] opened the fifth seal, I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. They called out in a loud voice, 'How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?' Then each of them was given a white robe, and they were told to wait a little longer, until the number of their fellow servants and brothers who were to be killed as they had been was completed" (Revelation 6:9-11).  

All these questions are addressed in Randy Alcorn's book Heaven (Tyndale, 2004). Most of them have clear, though not comprehensive, biblical answers. The others that don't have clear answers can be intelligently speculated upon, based on what Scripture does tell us.

A few months ago I happened to see this on The Heart of a Pastor Wife's blog, and thought these pictures were profound.
