Regarding ComplexExpand, your expressions for d, integral powers of  
Abs, are already in expanded forms acceptable to ComplexExpand. You  
want alternate forms without Abs. Tell ComplexExpand that,

ComplexExpand[d, TargetFunctions -> {Re, Im}]

and it will give you the answers you want.

Each new application of Simplify or FullSimplify is an adventure :-)
