I don't know if I'd consider myself an "expert," but I'm certainly advanced. Using frameworks is the way to start, as it's one of the quickest ways to understand how things can be set up. What I found, however, is that very quickly you will outgrow frameworks. They tend to become more of a constraint than they help when you're working on more advanced things. When you reach that point, you'll probably start to piece together your own favorite snippets into something that works for you - grids, resets, etc. So pretty much what eswat mentioned above. Just go into it with the impression that everything in a framework is a suggestion, and learn as much as you can, with the idea that you'll be doing it your own way soon enough. Later, you can get into things like BEM, or OOCSS, or SMACSS.
