For the time being, it really depends on what's available on the aftermarket and how deep your pockets are.

I've seen 3:55 and 3:92 and 4:10s mentioned here numerous times. No word on a 3:73 whatsoever. Most seem content with the 3:92s for what you say you want to do with your truck.

Now if you're just looking for ring gears (i.e. the ratios mentioned above) I'm sure there's a multitude of manufacturers out there: Auburn, MOPAR, Detroit Locker, etc.

As for getting a hold of a locking differential, for the rear MOPAR seems to be a winner here as it's "genuine parts" and you retain your warranty. As for the front, I haven't really seen much in regards to a locker.

I know that doesn't answer all or most of your questions, but this is what I've found so far. I'm sure the towing, hyper-miling, and off roaders here will chime in soon.
