"Praise to the man"
Praise and Worship are two different things. Here's an example:
'The citizens of the town praised the mayor for his commitment to education reform.'
Are the citizens worshiping the mayor as a deity? No. Praise is to express approval or admiration while Worship is the feeling or expression of reverence and adoration, usually for a deity.
"Kings shall extol him"
Extol means to praise enthusiastically, which is a way that shows intense and eager enjoyment, interest, and/or approval.
"Great is his glory"
Glory is the high renown or honor won by notable achievements.
"He will enter HIS kingdom"
Here, 'His' is referring to God, not Joseph Smith.
He (Joseph Smith) will enter into His (God's) Kingdom.

"' I have more to boast of than ever any man had. I am the only man that has ever been able to keep a whole church together since the days of Adam. A large majority of the whole have stood by me. Neither Paul, John, Peter, nor Jesus ever did it. I boast that no man ever did such a work as I. The followers of Jesus ran away from Him; but the Latter-day Saints never ran away from me yet…' (History of the Church, Vol 6, pg. 408-409)"

"The LDS Church offers praise to this man, who married and almost certainly had relations with mother-daughter pairs and pairs of sisters, over 30 wives in all. Marrying mother-daughter pairs and sister pairs was an act condemnable by death in Leviticus 18."
"Joseph knew the practice of plural marriage would stir up public ire. After receiving the commandment, he taught a few associates about it, but he did not spread this teaching widely in the 1830s...Joseph told associates that an angel appeared to him three times between 1834 and 1842 and commanded him to proceed with plural marriage when he hesitated to move forward. During the third and final appearance, the angel came with a drawn sword, threatening Joseph with destruction unless he went forward and obeyed the commandment fully."-LDS.org
..."the God of the Bible."
Is the same God in the Book of Mormon. We do not worship a different God.
"Brigham Young taught that “no man or woman in this dispensation will ever enter into the celestial kingdom of God without the consent of Joseph Smith.” (JoD Vol. 7, pg. 289)"
