I have a Premium membership so I can tell you that the answer to your question is Yes. In fact, not just a bunch of lessons, but every single one of them!
After you sign up you receive some introductory e-mails explaining how to use the website effectively. You get one a day and I think it's the third one that gives you link to a page from which you can download the material. It works using iTunes, so you need to have that installed and working before you try to do the download.
The link will download the names and a description of all the items you can download. There are a lot of them! Once the details have been downloaded you can click 'Get All' in iTunes to download all the files. It takes a long time: I left it running overnight and it was still doing it next morning when I got up. You get all the material (the audio tracks, all the PDFs and all the videos) and as new material is released, iTunes will download it for you. Altogether there are around 8,600 files adding up to 28Gb, which iTunes estimates adds up to a total playing time of 18 days.
In my opinion the Premium membership is a very good deal indeed. Go for it...
