I am trying to find out who the author of the following statement is: "a man should love his wife as much as he does himself and should respect her even more than he respects himself" - listed as Yevamot 62B.

It is a statement from the sages of the Mishna not related to a specific one, it appears in the Talmud tractate Yevamot as you stated and the source is from the tractate of Derech Eretz (of the Masectot Ketanot, Perek Haminin; 16)
