If a strong acid or base is dissolved in water, will all of its parts have the concentration?
For example in
Ca(OH)2 = Ca + 2OH
if the concentration of Ca(OH)2 is 8.11x10^-3 M, would the concentrations of Ca and 2OH be the same? or in the case of OH, the concentration has to be multiplied by 2 because of the proportion in the equation?

The latter. Ca is Ca(OH)2 and OH is twice that.
Remember that is true ONLY for strong acids or bases. If weak acid or weak base you must use Ka and Kb.
