Confusing items for the beginner (me)

David, I am new to the site and have navigated around a little. My ultimate goal is to go through the LOA program. My question is after I have watched the Welcome video and some of the basics, do I click on LOA and follow that through or do I click on lessons or is it a combination of both areas. This is confusing for me. Also just as a suggestion, I would really like to see any area or item that I have clicked on and watched to be grey or a different color showing that I have already been to this item. Of course I could always re-click and watch again, but at least I would know where I left off or that I have already been there at one point. Thank you.
