You might find it easier to use tables, these days its more 'correct' not to use them but if you are learning & using editing software like dreamweaver, its much easier to use tables to visualise what you want to do (i think it is anyway) & the software makes it much easier to edit the dimensions of cells etc.
Once you'v got a grasp of what your doing and are comfortable looking at code, then try to use css for the structure.
If i were you id start using tables for structure & css for text styling though. Im sure there are good tutorials out there to teach you how to use styles properly if you want to jump straight in with them.
