Being that the spark plugs have less than 30,000 miles on them, I think I should be able to get away with only replacing the coil? What do you think?

Amzon has the coil for what I believe is a great price. $54 https://www.amazon.com/Denso-6731306...832011&sr=8-14

You can replace the defective coil and you're good to go. but if i were you, you may replace the plugs too, they are cheap and it pays to replace them too. Manual says you can go up to 160k KM or 100K miles.

Where i sent my car previously (under warranty) they replaced them every 20K KM (at Toyota Service Center) and i happened to ask the mechanic about it. He said what is in the manual is if you are running normal RPM but in Saudi we average at 120-140kph at 3500-4000rpm since we usually drive on a freeway hence the need to change them earlier than required.

Right now i do my maintenance and replace plugs by myself at around 30-40K KM interval...
