Having a bit of a problem with polygon verticies on the hands and head....they won't connect with the body....... Any help in here will be appreciated......

I'm not sure if this would help you or not (I use 3dsMax), but try to 'attach' the models to one another. Perhaps there's a menu in which you can do this in Maya?

I hope this could help.

If they are two separate mesh parts select one the shift select the other part
then polygon/combine them select verticies you want to and merge them editpolygons/ munu.
