That book looks like a pretty expansive affair…wow, didn’t know anyone did things like that any more!
Personally, I’d try to work out what I wanted to learn and then search for the specific subjects individually. I find many general intro tutorials cover things I have no interest in in great depth and skirt over things I do. This is fine if they’re free (or cheap) as it’s always useful to have a rudimentary understanding of “everything” a piece of software can do. Once you’ve got a rough understanding of what it can do and indeed what you want to achieve the manual is pretty good resource too!
Do check out the free samples before spending any large amounts of money (the SWA free bits had me turning off straight away but these things are very personal). It’s all very well to have x hundred hours of tutorials but if the style is not to your liking you’ll probably never watch them.
