Whatever workout plan you decide on, make sure it includes a lot of explosive movement such as plyometrics. I am also a wrestler (although somewhat smaller, about 135 in season), and I have always found that in any excercise if you do explosive movement in transfers very well to wrestling strength. Also do more compound lifts that isolation movement, especially squats, deadlift, bent over rows, military press, etc. If you don't know a lot of exercises check out bodybuilding.com, great site with a lot of info. Im also a certified personal trainer if that makes you feel better lol.
