I love that quilt, too, and was very excited about doing it a few years ago. I did about 50 blocks and then kind of got it out of my system. At the time, however, I was keeping a log about the blocks and following a couple of online groups. I was also trying to keep the colors close to the original and found that to be stressful for some reason! So my advice is to have a plan and enjoy the process. I did a lot of the easy blocks by using the book as a guide and got the computer program as soon as I found it on sale. I highly recommend it! I used tracing paper in the printer so I could paper piece many of the blocks.
I really admire those quilters (and Jane, of course!) who have completed the quilt. I plan on making a small quilt out of my blocks.
