Your manual update was the update. You will get future updates unless you manually update those as well.
I don't think you'll get an OTA notification for 2.01 if you did it manually. But you will get future updates (e.g., 2.1 in January)...or at least that's what I expect. I updated manually and haven't heard/seen anything that leads me to believe that folks who updated to 2.01 manually won't get future updates.
No you will not. I did it manually and never recieved an update notification. My wife's droid did recive the OTA because it had the old system.
