Answer 1

You can not directly transfet ether from contract to EOA. Contracts are different from EOAs( Externally owned accounts) in the manner that EOAs are governed by private keys and contract is governed by its code.

SO if you are getting ethers in contract, you need a method to withdraw eth from the contract.

The code may look something like:

function payout () public onlyOwner returns(bool res) {
    owner.transfer(address(this).balance);
    return true;
}

Answer 2

You already have this function in your code. This should work:

    function withdraw() onlyOwner public {
    address myAddress = this;
    uint256 etherBalance = myAddress.balance;
    owner.transfer(etherBalance);
}
