If you've got Mike Lawson's video "Tying Flies for Spring Creeks", you've got all you need. I have both the "Japanese" Harrop video and the Lawson, and their methods for tying the no hackle are almost identical. Harrop does't take the thread up, he just goes straight back and straight forward with it, but beyond that there's no difference. The rest of the Harrop video is great though, so maybe you need it. Trouthunter has it.
