Problems with the front legs

Just wanted to post the images of the problems I've encountered with the front legs on my rig.  I did post the pics on CG Society forum and asked for help.  I hope that I will be able to get it all fixed.  I also played with the skin binding, and discovered that it's going to be difficult since I have so many polygons on my model.  But, it will get done.  I might live in the Mac Lab for a while, but it will be done.
