Welcome to the forum and to the lessons.
Beatriz can clearly type faster than me
and gave a great answer - she has made amazing progress over the past year or so by following these lessons, so you can trust what she says.
In response to your question about recording set-ups, it is possible to spend quite a lot of time and money and get a very professional result, but for the purposes of the lessons, I'm sure your current laptop will be fine (just test it out as Beatriz said). I recorded level 1 & most of level 2 with my mobile phone. I now have a much better mic, and it does make a huge difference, but the phone recordings were perfectly adequate (and I still use it for the video). Placement makes quite a difference, and I found that about 20-30 cm in front of the sound hole was a good starting point to experiment from. It really helps those who are giving feedback if you can get your left and right hands in shot.
Regarding the material, the lessons are pretty comprehensive and there will be plenty to keep you fully occupied. The Noad book you mention is highly regarded, as is the Sagreras method, which is free for download on this site. Sometimes it might help to see something explained in a different way.
@Beatriz - good luck in your ensemble group. I think it's really great that you have found such a group close to where you live, and I'm looking forward to hearing how you get on. Are you still going to take the Delcamp exam this year ? (you have probably completed enough of the course to qualify)
Thanks also for your kind comments - I think my contribution is pretty minor compared with the others, though. You are pretty inspirational here yourself, you know!
