The answer to the original question is rather straight forward, i.e. The answer is "no", unless you meet the following two requirements: (1) Are a male member of the tribe of Levi, and (2) are serving in the Temple. There are a number of additional instructions applicable to everyone, as pointed out in several other posts. The bottom line is "if an instruction pertains to you, follow it out of love for the creator, if an instruction does not apply to you, then ignore it. After all, not even Jesus Christ obeyed every explicit instruction in the Old Testament. Why? Because many did not apply to Him, e.g. the priesthood instructions found in the book Leviticus.
It is interesting to note that there are 1040 direct quotes/references from the Old Testament found in the New Testament, as complied by the Trinity College, Dublin. All of the so-called Laws are Instructions in Righteousness, that is, what God requires of mankind in order to satisfactorily obey/fulfill the Ten Commandments.
The most telling N.T. scriptures concerning the Commandments and faith in Christ are found in the book of Revelation: Rev.12:17, 14:12. and 22:14.
