Gary, as always (this and many other threads), great links and recommendations!
I'm glad you metioned not sealing the area in order to allow future possible drainage needs. I've been waivering on this issue in my mind, only because I was thinking that better sealing to the outside might help avoid critters getting in -- not worried so much about termites, but the darn fire ants in this region that sometimes like to nest in the exterior walls. I guess I'll need to figure out another way to deal with that.
I'm also glad you mentioned the link from your previous post, since I missed the 2nd one about attic ventilation. That's actually a discussion for a separate thread, whenever I get to that level of priority (which might be a while, alas). I not only have concerns about adequate intake vents, but my two power vents are dead (not a thermostat issue, apparently blown motors), and my two bathroom vents only exhaust into the attic (gasp/shame)! The joys of a recently-acquired home -- always plenty of inheritited problems to address.
