Trouble with Skin Weights

I assure you that I have been working on this since I got back from church this morning.  I cannot get the skin weights on the legs and body to work completely right and since my book shows an interactive skin bind and I'm using a smooth bind (because I tried the other and this one works better) I'm kind of in the dark about what I'm doing.  I hope I have a fully weighted and animated model on Tuesday, but it is starting to look like I'm not going to make it.
I did manage to get the ears to move close to right.  You can't tell that the skin around the base isn't quite right thanks to the fur (thank the Lord for furry animals).
