No. Expungement only makes your conviction hidden from the general public - it doesn't make it go away.
Have your record expunged or the conviction overturned.
California does have a provision for expungement. See the below link for further information on its requirements and procedures.
Yes, you are still a convicted felon, even after completing probation. You must get the conviction expunged to restore your rights.
Wrong. A felony conviction IS a felony conviction. You may be able to get the offense expunged (IF Arizona is one of the few states that will restore your civil rights).

You need to go to an attorney and/or the court and have your felony expunged from your record. This costs a fee and is ultimately a judge's decision.
A felony stays on your record until it removed. You can have most felonies expunged from your record and have your civil rights restored.
Generally speaking, yes. If you were never convicted, you can obtain a permit. If the charges were expunged, it depends. Expunged is not necessarily the same as having your rights restored.
Getting a felony expunged doesn't make it go away - it simply limits access to that record. A felon with an expunged record is still a felon, and is still prohibited from purchasing, possessing, or being allowed access to firearms and/or ammunition. That's a federal law, and it does not vary between states.
You will have to check with your own particular state's laws on this. Some states will expunge Domestic Violence convictions and some won't. Even if the offense is expunged that does not mean it 'disappears,' it only means that the general public won't be able to see it. Law enforcement, the courts and government agencies will still have access to your "true" record and that may prove to be your stumbling block to firearms ownership.
Having it expunged doesn't restore your firearms rights - you remain a convicted felon, and thus, are prohibited from possessing a firearm under federal law. If it is only a felony at the state level, it MIGHT be possible to have your firearms rights restored. You'll need a lawyer to give you a more insightful answer here. If it's a federal felony, you can pretty much forget it.
With enough money, lawyers and time, it might happen.
