Good luck, and, yes, the setup sounds good! You could dampen the paper towel a bit to be safe, but it'll probably soak up the condensation from the bag and become damp that way. (Also, a lazy trick for keeping seeds warm without a heating mat, if your house isn't too cold yet - you can leave them on top of the fridge...that worked for me in a room that was in the upper-60s-to-lower-70s Fahrenheit.)
Extra note - since I see from the labels that you're sprouting habaneros (good choice!) and scotch bonnets, don't worry too much if they don't sprout within a week, or even several weeks. My orangeish-yellow habaneros took around three weeks to sprout at the earliest, and other seeds began to sprout after I dumped all of them into a soil tray. (Some Thai hot chiles sprouted within a week, though, so checking on them is smart!)
