comment Fundamental Unit In Algebraic Fields
What in particular confuses you, and what kind of background do you have? It is easier to address particular issues than try to explain the full proof.

Look up Dirichlet's unit theorem.

comment Dummit and Foote page 591
Why do you think such an element $\alpha$ exists? $\mathbf{F}_p$ being perfect implies that the unique $p$th root of every element of $\mathbf{F}_p$ also lies in $\mathbf{F}_p$.

@Brian: There weren't enough details originally. The OP added details after I made my comment.

comment Showing that $A^*$ is and ideal and that “$*$” is multiplicative.
@Kplusn: The construction of the extension of an ideal takes the ideal generated by several elements (in this case the elements of A). It is, by definition, an ideal.

comment Showing that $A^*$ is and ideal and that “$*$” is multiplicative.
It's a special case of ideal extension coming from the obvious inclusion $\mathcal{O}_F \hookrightarrow \mathcal{O}_E$.

comment Demostrate: $M_p=2^p-1$
There are many different definitions of pseudoprime, as you can see in your Wikipedia link. Which one are you working with?
