Agouti is the base colour of all mice. The 'wild' colour.
Your albino mouse is probably agouti, carrying black, and not carrying piebald. Agouti is a dominant gene, so one copy of it is enough to make the mouse agouti, whereas you need 2 copies of the recessive gene black, to make a mouse look black. Albino (p/p) covers up all other genes. The other genes are still there, but albino is like painting the whole mouse white over the other colours. This mouse must have one copy of Agouti, and one copy of black, because it produces both black and agouti babies. The mother is obviously (a/a) two copies of black, because she -is- black. 
So here are what I think the genotypes of your parent mice are.
Albino male:
A/a (one copy of 'A' agouti, and one copy of 'a' black)
p/p (albino)
S/S (no copies of s, no spotting, big S represents nothing, in this case)
Moo:
a/a (black)
P/p (one copy of albino, so she is not albino, but produces albino babies with your male since he has albino genes too)
s/s (s is piebald spotting, it is recessive, so you need 2 copies to have spots)
All of your babies should be S/s because they have one s from their mom, and their father doesn't have any, so that is represented by a big S. So if you breed any babies together, or back to Moo, you should get piebald babies. As far as colours, unless the mice have hidden recessives, there will be no colours other than black, albino, and agouti. 
Solid colour is self, agouti is listed as AOC (any other colour) because each hair instead of being one colour, is striped black and brown, instead of being just black or just brown. Solid brown, is chocolate, by the way.
