www.craftsman.com has many hundreds of plans, according to the site info. I looked at one for a blanket chest. The plan is three-dimension, making it easy to understand how the parts relate. One page showed how to make efficient use of the material required.
I haven't used any of Norm's plans, but he has done a number of chests.
Even though it is your first case work piece, I recommend these two books to develop your design skills and construction knowledge. Although you could use them to design your chest of drawers from scratch, it's probably better to use them as a reference for construction and changes that you may want to make.
