Cold air intake won't really help you either. 
The stock systems are actually pretty good, and are already "cold air" systems. More or less...... These remind me a lot of throttle body spacers. They hype is good, but, in the real world, they only lighten your wallet.
If you haven't done gears before, I highly recommend you pay someone else to do it. (expensive, and for a reason.) Either that, or have someone that has done it before help you. There are some special tools involved, and you get ONE chance to do it right. Do it wrong, and you can damage the get gears, or even destroy the differential...... Gear set up is an art form, and not many shops will even attempt it.
Your two rating isn't going to change. Going to the bigger tires with stock gears actually LOWERED your towing ability, changing your gears to go along with the larger tires will simply put you back to basically stock specs.

I have an 05 4.7 and geared mine to 3:92. It does the job but grabted i dont pull as much as you are. As for the electric fan converstion. I did it and i can tell you from experience that it does NOT add 10 hp. At most it adds like 1-2. It does however help alittle bit with the mpg. I have never heard of the pcm controlling the mechanical fan clutch. To tell you the truth i dont think thats even possible. Ive done both setups as far as the fan. (Made my own/bought one). I can tell you from experience that the purchased ones work alot better and last alot longer. Im on my 3rd setup the first 2 i pieced together. I didnt like the way they performed and the fans didnt pull enough air because i had to use the original fan shroud. I could really tell pulling a trailer in the summer. I finally bought a flex-a-lite kit from amazon. I came with everything i needed and you dont use the original fan shroud. So far its working 10x better than the others. Yes it was kinda expensive but to me it was well worth it in the end.

Well the toy hauler is only 5400 lbs. Only will be pulling it 3-4 times a year. Say stock with the rear end that's in it, should pull 6200 from what I recall.it actually pulls it just fine. I replace the rear shocks with some load leveling ones that have coil springs on them too. Was just wanting a little more power and better gas mileage. Transmission has the tow haul feature. Just don't want it to struggle and wear out early. Love my truck and don't want to replace it.

I haven't done anything with the gears yet. Don't know if I'm going to. I went to a 4x4 shop and they suggested I don't do anything unless I absolutely have to do. I have replaced the rear shocks with heavy duty ones. Gonna put an air lift set up on it next. Have a runer, cold air intake, and electric fan.
