Is the mitochondrial DNA in a baby more like the mitochondrial DNA from his mother's mother or the mitochondrial DNA from his father's mother?

It is exactly like the mothers (except for some possible random mutations). The mother's egg has all of the cytoplasmic components inside it. The sperm only carries DNA. So mitochondria are maternally inherited.
While the sperm does contain mitochondria in its tail, only the DNA from the head are transported into the ovum.
The DNA of the child consists of half the genetics of the mother and half the genetics of the father. This is because the sperm carries 22 chromosomes and an extra sex chromosome (X or Y). The egg inside the mother also carries 22 chromosomes and a sex chromosome (X or X). When these meet we get 22 sets of chromosomes and a set of sex chromosome (X,Y or X,X) which determines the gender of the child. However, if the mother or the father is carrying an extra 21st chromosome and for example, the child receives 2 21st chromosomes from the father and 1 from the mother, they now have 3 21st chromosomes which can lead to the child being born with downs syndrome.

What would be expected if a woman with blood type AB has children with a man who has blood type AB?
That would depend on whether the bloods types are both negative or both positive or one of each, If the blood types are both the same then there will be no problem, if the mother has negative blood and the father positive, the baby can be born "blue", which basically means the mothers blood being negative is trying to destroy the fathers positive antibodies from his blood in the baby, this is not too much of a problem as midwives will administer an "anti D" injection to the mother to protect the baby, if untreated the baby will be born with blue lips, toes, fingers and other extremities, a blood transfusion usually sorts any problems and does not have any long term problems for mother or baby.
