With the 3.0 gear the standard T-5 will probably be fine.  The Fox's came with 2.72 gears and that seems to have worked.  With any lower (higher ratio) gears you'll probably find that 1st gear is about useless so what you have should be fine.  If you ever decide to get better off line performance and go to a 3.55 or 3.73 gear you'll probably want to change to the Z spec T-5 gear-set which has taller (lower ratio) 1st and 2nd gear and a .63 OD rather than the .68 of the standard T-5.
