Good to hear you're going to Sac-Anime! I may be going as well, not quite sure yet.
For Naruto cosplay, I think you'd make a good Itachi, Shikamaru, or Sasuke.
Non-Naruto, I'd suggest Phoenix Wright from the video game series, Squall Leonhart from Final Fantasy 8, or Great Saiyaman(Gohan) from Dragon Ball Z.
I kinda look like you in real life(5 ft 9 inches, 150lbs approx, Asian male). It's generally better to be taller for cosplay, so lucky you.
Cosplays: Yuri Lowell(Tales of Vesperia), Gaius(Tales of Xillia), Sesshomaru(Inuyasha), Dias Flac(Star Ocean: The Second Story), Amethyst Ashe(League of Legends), Yu Kanda(D.Gray-Man), Deidara(Naruto: Shippuden), Shinji Ikari(Neon Genesis Evangelion)
