"This here" is a drop-in replacement for "this", and is mainly used as an emphasis marker in the South and West. Adding more words that do not add to the meaning of the sentence makes it the same idea, but more of it. Compare: We have a communication failure. What we've got here, is failure to c'mmunicate. "Have" is the base word. "Have got" is the same as "have", but with more "havingness" somehow. "Have got here" is also "have", but with so much "havingness" that you might find yourself unable to get rid of whatever it is without a severe beating. And with "what <subj> have got here is", well, you're just going to get shot.
