1. As for the question of the amount of goods - I am in ME, running around 50-60 RQ per day, with CF level 10, I do around 4400 Goods per month (this includes GE4 rewards and ToR level 10).
2. As for the question of Traz vs. CF and GE.
IMO, the most important point is whether you finish GE64 every week. I wasn't sure from your answers if you manage it just twice, or you finish it every week. You should finish it every week no matter what as soon as possible. GE64 should be on farm for all the goods/FP/Diamonds/TF/ et cet.
In the short run, with the CF it would be easier to finish, as the last fights are the hardest and negotiation is much easier to do then fight. So maybe level a bit the CF until you have enough goods to do GE every week.
For the long view - Traz is a hugh saver on space (as was written above), and the troops for the GE + rogues from the Traz should furnished you with tons of troops to finish as much of the GE with fights.
You will also have to level some attack GB's for this way, as the Traz alone is not enough for the hardest fights. Once you got the Traz and finish GE only through fights, all your goods will be saved from negotiation and you can use them elsewhere. So the Traz option is the most efficient in the long run for a city - in space, happiness and goods (and troops of course).
But, as I said, its not just the Traz, you may have to level the CoA/Zeus/CDM. The amount of FP is rather low, as in HMA you should aim to around 60% attack bonus which is around level 7 for all 3 attack GB's together. Thats a few thousands of FP, which are not a lot in the long run, but needs to be counted and decided if you want it.
