  2. Can I only begin mining once the sync completes and -
  3. Can I switch back to the main network without losing what has already synced in the Test-Net?

If you are solo-mining, then yes you need to download the blockchain (it's separate testnet vs mainnet).

Yes solo-mining requires that you have the blockchain already up to date.

Yes you can switch back and forth without losing current status.
