You sound better prepared to escape a fire than most already - scanning photos and copying your vital docs to a safe deposit box puts you way ahead right there.

I would separate your scenario in two: escape from a fire in your house, and escape from an external fire (wild fire approaching your house). I don't have the possibility of the second here in urban PNW, but everyone has the first scenario. I'll let someone more experienced comment on the wild fire scenario.

First scenario: get OUT, and stay OUT. That means a plan for getting every loved on out of the house, even if the fire blocks the usual exits. On this one I think its good to have the kids do some of the planning and internalize the plan that way, Scholastic recently had a Fire Safety week for which they posted plenty of materials - http://scholastic.com/firesafety/. Make sure your kids have a plan to escape independent of you, and a gathering place afterwards. A hallway may be blocked with flames, you may only be able to get out and go to their window and try to assist them. Better if they didn't try to escape down the flaming hallway, or you come to their rescue, but to crawl out a window.

Practice the plan. The switch to daylights savings time is as good a time as any, replace your smoke alarm batteries and run a 3 minute fire drill. #1 son gets a kick out of getting to crawl out his window and beating us to the rallying point. He was halfway to the next door neighbor's to inform them our house was on fire, which would have been a bit of a surprise for Bellevue FD.

Get OUT and stay OUT, no regrets. There's nothing to run back into the fire for. Precious memories and assets may be burning in the fire, you have to let them go. You've already done your best, by preserving family photos and other stuff and putting them in your safe deposit box. Urban fire response is fairly quick, odds are good they'll save some of your things.

Don't sweat the BOB if your house is on fire. Don't sweat the change of clothes either, if you have family or friends to stay with they can make a trip to Target or Macys for you the next day. If you're more isolated the Red Cross generally has resources to help you. Alive in your underwear or robe is more important than 40% burned holding a BOB. Grab your shoes if you can, but remember the fire department will be on scene quickly, your adrenaline will be pumping, you have neighbors with warmth and blankets you'll do fine even if its cold outside. Get you and your loved ones OUT. Underneath my bed are a pair of shoes, socks, pants, shirt, fleece jacket, flashlight, hardhat gloves, crowbar and gear for turning off gas and water - earthquake stuff, to get out of my bedroom and out of the house. At most I'll grab my shoes, flashlight and the crowbar if the smoke alarms go off.

Expect the unexpected. You've reached the safe rally point outside your house, its pitch dark, smoke is coming out of your home - your youngest daughter isn't there. You hear sirens approaching your house, help is on the way - what can you do? Heroics are constant, you may feel compelled to run back in, but the question is situational - how you respond will depend on the actual circumstances. I don't want to answer this part of the scenario for anyone, just think it through a bit and know what your options are. Breaking her window might accelerate the fire in her bedroom, to this point its been heavy smoke, with an open window it now has a supply of oxygen to fuel it. Her best chance of survival may come from fire fighters entering with their oxygen masks and searching her out. Lord, I hope I never have such a decision to make.
