yes, vac out the water as much as possible - then try and blot some more out with a towel....
afterwards try and leave the vehicle with the doors/windows wide open to air out the interior, do the fan thing that RCG said....
finally, get some fabric "odor remover" (febreeze, although I like the smell of TW Odor-X better) and spray it on all upholstery.
This should take care of most of your mold probs. that could occur, just be sure after the car's all dried out that you shampoo all the carpets and scrub really well, and wipe down all vinyl/rubber/other porous surfaces with a cleaning mixture (for this, I use extremely diluted [~1/4 oz. per 1 galon H2O] simple green, some tide laundry soap, and oxiclean mixed together in a WARM solution. - this is for both carpets and other surfaces)
use the mixture, and really saturate the interior with the soaps and stuff, just be sure to scrub them really well and vacuum the water out - follow the same airing out procedures.
Hope this helps - sucks when stuff like that happens!!
