General consensus on here is the 460 will consume a lot of fuel with 4.10 gears or better and when towing but you're not buying one of the biggest gasoline engines ever produced for fuel milage so that's probably not a big concern. I'd say you want 4.10 gears for sure.
i wouldnt swap your until i tried pulling the trailer or one of similar weight, that said 4.10s do good up to 33" tires with a trailer under 10k lbs, my 3.73s had no problem with close to 10klb trailer when i had 33" tires

For that weight trailer, Ford recomended the 410. anything more would only tend to be a waste of fuel...I would'nt go for the 456

One other thing to worry about... with some transmissions the overdrive is actually weaker and towing in OD will lead to early failure. I know for a fact the ZF is one, but I don't know if the E4OD is or not. I would head over to the tranny/axle/t-case forum here and see if you can get Mark Kovalsky's attention. Ask him if there is a problem towing in overdrive with an E4OD.
But I agree with the 4.10 gear ratio.
