The on-line pass has a service fee of $2. Also, due to travel uncertainties, I'm not sure exactly how long I'd get once I'm there at Niagara Falls. So, once I reach Niagara, where can I buy the Discovery Pass - is it available at the ticket counters for popular attractions such as Maid of the Mist, Cave of the Winds etc?

According to Wikivoyage, you can buy the Discovery Pass at any of the attractions that it includes - ie Cave of the Winds, Maid of the Mist, the Gorge Discovery Center, Aquarium, Adventure Theatre, or Whirlpool Tours.
You can combine all these attractions with a Niagara USA Discovery pass for $35, which you can purchase at the attractions.
