I like to do front bearings everytime I do the brakes and also anytime you go through a deep water crossing. The rear bearings are all lubed from the diff oil and don't use grease.
I check mine every time I break an axle 
With the type of wheeling I do it seems like I am in deep mud at least once or twice very 6 months so I tend to mine twice a year if not more. Well usually I just do the outer the inner seems to last alot longer. Plus I hate buying that stupid seal its expensive on a 60

how long should the wheel bearings last? how about the axel bearings?
Front bearings that are kept properly greased will usually last a lifetime BUT the one thing that will kill any wheel bearing is running a wheel with a lot of back spacing.
Rear axle bearings will usually last a lifetime as well if the diff oil is kept full. Once again running a wheel with a lot of back spacing will prematurely kill the bearings as well.
If I was going to replace my rear bearings and seals, are there any good brand names to install or would my local O'Reilly's stock stuff be OK? 10 bolt with 35's on it.

Timken is kinda the standard...Some folks run Koyo bearings... But personally ive seen far too many of the prior model dodges(w/d60FF) come into the shop with less that 40k on the ticker with failing pinion and carrier bearings(all turned out to be Koyo) to put any of them in mine-friends-or customer's vehicles.
Just pull the bearing out of the box and look at it, see if the timken name is there

Why does tha backspacing affect the bearings? i always assumed bigger tires would chew the bearing prematurely... also where do get the timken's ive search a couple of places and havent found them, and Napa has china and spain stuff.. wich both suck by the way i preffer mexican if i had to choose from thoose 3.
Personally i check my bearings before and after i go out to the trails if i hear something around the i will check them to.

The further out your wheels are from the hub mounting surface the further the weight is. It acts like a lever essentially adding weight via hanging force.
250lb guy on one end of a teeter totter, 150lb guy on the other end. Nothing budges. Move that 250lb guy closer to the fulcrum point and all of the sudden the lighter guy on the end picks him up no problem. Mechanical advantage.
Autozone had one....

Last time I bought front 60 bearings, autozone was the cheapest for Timkens. Your local truck/equipment/driveline shop may be able to get you them cheaper though. I get my bearings, seals, ujoints from my driveline shop for about 10% cheaper than online even.
Lots of backspacing means that the wheels are moved closer to the center of the vehicle, no backspacing would mean that the mounting surface of the wheel is even with the inside of the rim of the wheel and all of the tire would be away from the center of the vehicle. Lots of backspacing, especially with wide wheels, would move the offset closer to 0 which would mean less leverage on the bearings.

ok so what would be a bad number for backspacing, almost everybody runs 3.5" os bs (backspacing not bullshi...haha)
i repack them everytime i replace them.
