If I donate and upgrade, does my account become Gold instantly?

Yes, as soon as you’ve made a successful donation, your account is automatically upgraded to Gold. It’ll remain upgraded until the end of the one year period (and then be downgraded again and no further donations taken), unless you check the ‘Make this Donation Yearly’ box, upon which your nominated PayPal account or bank will be automatically charged and your account upgraded for another year. In this case, you can cancel the donation payment agreement anytime here.
