"...California will give you a partial credit for taxes you paid to Arizona..."
Not correct. Just to be nit-picky: CA and AZ are "reverse-credit" states. That means that the "other state credit" (when applicable) is granted by the non-resident state. A CA resident with AZ-taxable income would claim the credit on his non-resident AZ tax return, not on his CA tax return.
CA will not give a credit for taxes paid to AZ.
