>> As long as you change the effected outlets and boxes you will be fine. there is absolutely no reason to change all the wiring. Whatever was wicked up into it would be so minimal it will likely be dry by now. Its not like the wiring is holding gallons of water. And truthfully, the only reason you have to change the outlets and boxes has nothing to do with the wetness, its because the water left sand and other crap in them.  (most outlets will work even if they are soaking wet as long as the power doesn't make its way to ground)
@ZMAN:
Unless you have the old cloth wrapped or aluminum wiring. Should be changing that out anyway.
@ET:
Believe it or not, half my house has aluminium wiring but its all wrapped in rubber coating.  I don't think any of the houses in Kingwood are old enough to have the cloth wrapped wire, do you? My house was built in 65 and has some additions, so I think all the original part of the house has the aluminium. For the most part its fine and I'm not worried about it, really the only downside to the aluminium is that you have to use a special paste (Noalox) and/or special wire nuts when connected directly to copper to prevent oxidation. 4951
