Is there specifically something we need to know about the 2 cell, 4 cell and 8 cell, 16 cell stages of cell?? I mean morula, blastula and gastrula neural makes sense.. how do we catagorize the 2-4-6-8-16??

Good question.

The only 2 things you need to know about it is:
1) Its during Cleavage
2) The cells get smaller because with each cleavage you are getting more cells using the same amount cytoplasm.

And i believe the cells are still undifferentiated.

i believe at 32 cells it is called the morula?
that develops to the blastula, which has the ICM and trophoblast right?

^correct
64+ cell-stage is referred to as the blastula, but blastocyst in mammals.

2-4-6-8-16??
there is no 6.
2-4-8-16-32-64...
