No it's not, not according to the Jewish people of whom you now claim to be part of.
The Jewish people do not study the OT without the Talmud according to their religion.
According to the Jewish religion, the Torah is the Law of Moses, the Talmud and the Mishah, and the OT. You seem to be having trouble either understanding that and accepting that. I have repeated it over and over again.
The Talmud and the Misha are the oral Torah. They are not part of the Bible and the Bible does not contain either the Mishna or the Talmud. Christian believers do not refer to the first five books as the written "Torah".
You are wrong if you believe the first five books of the Bible or the TaNaKh (or Tanach) are not the Torah. That is what the T stands for. The Jewish Bible is the Torah. The Hebrew Bible is the TaNaKh. The New Testament is often seen to be part of the Christian Bible, with the first part being called the Old Testament. The New Testament Writings, or New Testament Scripture, is for Jew or Gentile, whether you are already a believer or not, as with the rest of the Bible though many are without the Law or not a part of Israel.
As for the Mishna and the Talmud I have not studied them in their entirety. The Oral Torah is indeed also Torah. It is on the level of scripture. But the TaNaKh and the New Testament come before the Mishna, and as much as the Mishna explains the Written Torah and the details of the Torah or the Law according to the six orders, and as much as you will not understand the Written Torah apart from the Oral Torah, you can understand the Written Torah and you can stop there. I encourage you to read the entire TaNaKh, or Old Testament, as well as the New Testament. It is these that make up the Bible. As a Christian it is all for you. As someone grafted in you may be of the one new man and not need to be circumcised or observe all of the Law of Moses. But you ought to obey God, Jesus, and God's commands as He has revealed them to you in His word, the Bible.
Michael Chighel (in his course,
"Scroll Down" about the Torah and the Jewish Library) says, "The Mishna is an encyclopedia or rather an encyclopedic digest of all the laws and decrees of the oral torah."
It's divided into six orders.
