Ofcourse Satan knew Christ was God in the flesh!
God cannot be tempted with sin, but the Second Adam could be.(remember-two natures-one Person)
The temptation was for Christ to use His own Deity and not to depend on the Father (make stones into bread-no mere man could do that).
As for Christ's baptism, that had to do with the offical beginning of His earthly ministry, hence the Holy Spirit and the Father were both present.
Right, two natures in perfect harmony (not exactly a new "Adam" who was only one nature in one person, none of which was divine). But, you will tell me that my Church teaches that Christ was "New Adam." I know. I don't see it that way. I guess I am un-orthodox Orthodox, Leo Tolstoy's style.
The devil doubted that Christ was a perfect God and a perfect man in one Person. If he believed it, he would not have tried to tempt Him.

The Holy Trinity is eternally one in essence and inseparably Father-Son-Holy Spirit. There was never a "time" when the Word was not with the Father, or the Holy Spirit with them. Christ's "own" divinity is not "His" own; there is only one divinity, one nature that is divine.
The Gospel was written without a clear understanding or revelation of the Holy Trinity (thus the refrences to HS descending on Christ at Baptism and "leading" Him intot he desert), just as the Apostles did not fully believe or understand Christ's mission or, for that matter, who He really was, from the beginning.
That gradually changed in time.
