It's a complicated subject.
It's best to not side-track this tread into discussing the Trinity - lots of Trinity believers get upset by it and react in a non-Christian way, to such an extent that the administrators of the forum have banned its discussion. (I disagree with that; they should just discipline those who don't discuss the subject in a civilised way, such as imposing temporary posting bans, not ban free speech on a very important subject.)
But to address the points and verses that you quoted:
Does Jesus expect us to do miracles? (yes)
Did he do miracles in his deity, or in his humanity? (humanity)
No humans (including you, me and Jesus while he was human) can perform miracles. God performed the miracles. Hence Jesus said:
John 11:41 (WEB):
(41) So they took away the stone from the place where the dead man was lying. Jesus lifted up his eyes, and said, “Father, I thank you that you listened to me.
John 5:30 (WEB):
(30) I can of myself do nothing. As I hear, I judge, and my judgment is righteous; because I don’t seek my own will, but the will of my Father who sent me.
John 5:19 (WEB):
(19) Jesus therefore answered them, “Most certainly, I tell you, the Son can do nothing of himself, but what he sees the Father doing. For whatever things he does, these the Son also does likewise.
Philippians 2:5-7 NIV
In your relationships with one another, have the same mindset as
Christ Jesus:
6 Who,
being in very nature[
a]
God,
did not consider equality with God something to be used to his own advantage;
7 rather, he made himself nothing
by taking the very nature[
b] of a servant,
being made in human likeness.
Paul was talking about humilty:
Philippians 2:3-4 (WEB):
(3) doing nothing through rivalry or through conceit, but in humility, each counting others better than himself;
(4) each of you not just looking to his own things, but each of you also to the things of others.
and gives the example of Jesus, who, before his change of nature to become human, was a mighty spirit being, similar to God, yet he did
NOT consider equailty with God as something he should try to attain (unlike Satan, who wanted to be like God, and grasped his opportunity):
Philippians 2:6-9 (WEB):
(6) who, existing in the form of God, didn’t consider equality with God a thing to be grasped,
(7) but emptied himself, taking the form of a servant, being made in the likeness of men.
(8) And being found in human form, he humbled himself, becoming obedient to the point of death, yes, the death of the cross.
(9) Therefore God also highly exalted him, and gave to him the name which is above every name;
God does not exalt Himself! He exalts His only begotten Son (there's no Trinity there, just God and His Son). Jesus never claimed to be God; he only claimed to be God's son and the Messiah (anointed by God), e.g.:
John 5:25 (WEB):
(25) Most certainly, I tell you, the hour comes, and now is, when the dead will hear the Son of God’s voice; and those who hear will live.
That's why Jesus was crucified, because he claimed to be the Son of God and the Messiah:
John 19:6-7 (WEB):
(6) When therefore the chief priests and the officers saw him, they shouted, saying, “Crucify! Crucify!” Pilate said to them, “Take him yourselves, and crucify him, for I find no basis for a charge against him.”
(7) The Jews answered him, “We have a law, and by our law he ought to die, because he made himself the Son of God.”
After his conversion, that is what Paul taught:
Acts 9:20 (WEB):
(20) Immediately in the synagogues he proclaimed the Christ, that he is the Son of God.
