We shall all rise bodily...you mean symbolically or their flesh will come back even though it has been decomposed on Earth?
I mean literally. Our flesh shall be restored to us and reunited to our spirits, which await that resurrection in Paradise. St. Paul speaks of "spiritual bodies" (soma pneumatos) in the resurrection. We see what some of this may mean through the resurrected Christ, who was in the flesh (he did not receive a new flesh, for if he had, his old body would still be in the tomb. But, the tomb is empty...it is the same flesh! However, it is "new" and "spiritual." I guess a good way to say it in Orthodox terminology would be, "our bodies will be fully divinized." For the break of communion with God caused by the Fall shall be removed.
Why do the saints intervene on our behalf?
In mentioning this, I meant to highlight the activity of the departed saints (both those revealed to the Church and those only known by God) while they await the resurrection. The departed faithful (what the Roman church would call the "Church Triumphant") pray and intercede before Christ on behalf of those who are still living (what the Latins would call the "Church Militant").
And we don't get to see God?
I'm not sure what you mean by this. If you mean, prior to the final resurrection...I would tend to say yes. While I believe this would be theologumena and not established doctrine of the Church, the Gospels record in the parable that Lazarus, the begger who had died, was seated in Paradise at the right hand of Abraham. In the Apocalypse of St. John, the prayers of the departed saints (the martyrs specifically, who were the only saints as we understand them today, at the writing of the book) rise before the very thone of God:
"And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held: And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled." (Rev. 6:9-11).
