Running any two of IG, TF, or FM together is a waste of gold. Pick one and build something else worthwhile so you're not doubling down on procs when you only need one to be effective (IG or FM's proc are more reliable than TF anyway).
Quite frankly, AP/AS Jax should run:
Sorceror's Shoes/Mercury's Treads - 1100-1200 gold
Iceborn Gauntlet (15% CDR) 40 AP - 3400 gold
Nashor's Tooth (20% CDR) 65 AP - 2500 gold
Guinsoo's Rageblade 40 AP (+32 with maxed item stacks) - 2600 gold
The above four are core items on AP/AS Jax and easily max out CDR (@ 39%, 1% shy of 40%) with 4% in masteries, providing a potential 177 AP from items for 9600/9700 gold. The final two items are situational.
One of Hextech Gunblade, Will of the Ancients, Zephyr, or Manamune into Muramana
One of Wit's End, Abyssal Scepter, or Twin Shadows for magic resist purposes if necessary, or alternately a Zhonya's Hourglass if that AD Carry is causing lots of grief.
