Analysis: Quran Confusion

It is always interesting when reading what the Quran says about Pharaoh. I mean, with the Tower of Babel and Haman running around during his time period according to the Quran, I am pretty confused when looking over that part. I then realised, did Pharaoh even die according to the Quran when Moses split the sea?

Was Pharaoh killed or not killed by drowning?

"We took the Children of Israel across the sea: Pharaoh and his hosts
followed them in insolence and spite. At length, when overwhelmed with the
flood, he said: "I believe that there is no god except Him Whom the
Children of Israel believe in: I am of those who submit (to Allah in Islam). (It was said to him): "Ah now!- But a little while before, wast thou in rebellion!- and thou didst mischief (and violence)! This day shall We save thee in the body, that thou mayest be a sign to those who come after thee! but verily, many among mankind are heedless of Our Signs!"
(10:90-92).

Moses said, "Thou knowest well that these things have been sent
down by none but the Lord of the heavens and the earth as eye-opening
evidence: and I consider thee indeed, O Pharaoh, to be one doomed to
destruction!" So he resolved to remove them from the face of the earth: but We did drown him and all who were with him,"
(17:102-103).

If your confused, so am I...

Did the deity of Islam save Pharaoh or drown him? And after we get by all that, why on earth do is Haman in this time period and the Tower of Babel as well!
