Okay first of all how can you compare two totally different subjects. Shirk is when you are no longer a Muslim and you don't believe in anything that they believe and tawheed is basically the study of the Quran and Allah s.w.t. in Islam.
mt ---> shirk means ascribing partners with God. Disbelieving in HIS ONENESS.
We must know Who Allah is and how we should believe in Him.
In a reply to the question posed by the Non-believers of Makka (Mecca), Allah Almighty revealed a Sura Ikhlas (112) in the Qur'an telling the people Who the Creator is: Translation from Arabic language:
"Say (O Prophet): He is Allah, the One and Only, Allah is Eternal and Absolute, He begets none, nor is He begotten, and there is No One like Him." The in-detail study of the holy Qur'an reveals to us the facts about Him. He is the Sole Creator, Sustainer, Provider, and Ruler of all the worlds He has created. He has No Son, No Off-spring, No Parents, No Associate whatsoever. He enjoys Absolute Authority over all creatures. He is Most Merciful, Oft-Forgiving, All-Knowing, All Listening, Omni-Present, Omni-Potent. He shall never forgive a person who associates anybody else with Him in His Absolute Authority.
ShirK means that you know that there is a Supreme Being Who has created universe. But along with that Supreme Being (Allah-God) some one attributes the powers to others-Idols, priests, holy men etc.- which only Allah Almighty enjoys. That is associating Partners, Son, or somebody else to Almighty Allah. If somebody prays to, begs from, takes somebody his beneficient, or thinks him to be capable of doing harm without the Wish of Almighty Allah, he commits Shirk.
Tawheed is the belief in the Oneness of God, and is the most important concept of Islam. It is an Arabic word that comes from the root letters "whd," which is the same root for the number one in Arabic (Wahid) The three types of Tawheed are: Tawheed ar-Rububiyyah-- Oneness of Lordship Tawheed al-Uluhiyyah-- Oneness of Worship Tawheed al-Asma was-Siffat-- Oneness of Attributes
