kvnwpts, I can wholeheartedly recommend the SitePoint references. They're extremely good for learning, better than tutorials for me, because I like the more thorough, academical approach to learning. A tutorial will only show you so much, but these references give you an in-depth understanding of the core principles, methods, and how to apply them when and where.
For layouts in particular, I recommend these reading lectures:
They were written by Tommy (AutisticCuckoo), who is also the co-author (along with Paul O'Brien) of the SitePoint references. Tommy is to HTML and semantics what Paul is to CSS.
I'm posting these because I have the feeling you're really keen and eager on becoming a professional designer, so the reading material above is good to have in your arsenal of learning references.
