I have used Richard Haw as a resource and also on YouTube there's a guy named Kenneth (mikeno62) who is also very much worth checking out. Unfortunately, for the beginner who just wants to repair a lens or two, there really is no comprehensive resource that will provide all the information you need to complete the job (far from it), nor does anyone explain how the lenses work - what each part is named or what it does - but these sites do help. For example, I have had to figure out myself how to adjust the focus, which you will find is extremely important (I have had to reset the focus on about 1/2 my repaired lenses). By reset I mean so that the infinity mark is actually set precisely at infinity. There is no explanation of this online, anywhere.
If anybody here ever does consider diving in to lens restoration, please don't hesitate to contact me with questions. I am no expert and may not be able to help, but I do have experience with about 15 lenses so far and no failures, with 7 currently on my bench. I have cleaned elements and helicoids (and re-greased them) but I don't touch aperture assemblies!
