see Data Modeling (http://www.utexas.edu/cc/database/datamodeling/) for a good introduction to data modeling and relational design

the best tools for creating logical models are paper and pencil

for very large models, you can use Graphical Modeling Tools (http://www.methods-tools.com/tools/modeling.html)

Logical Design is basically a layout or the structure of how the project/business will flow from scratch going to the objective of the whole process. Normally, these fundamental steps are not so technical at the start, just guidelines or blueprints of how a certain processing will progress or "flow". Then from there softwares and techical designs will step in.

Yes a Data Flow Diagram is still a logical design as long as it compasses the whole process. It actually depends on the terms used.
