(This is a good site for looking words up, it has the romaji, and you can click on stuff to get the kanji or katakana)
Thomas means "twin" and Hooker is likely a profession name having less to do with prostitution than having to do with either fishing or hooking together things as in stitching. So the best equivalent of my name is...
爪双子. It's written as Tsume Futago (but pronounced as above).
