Do you want a material specifically only for categorical variables? or a material on logistic regression?
Either way, I'd suggest a book called " Statistics for Business by authors: Anderson, Sweeney and Williams". A wonderful book indeed. Have fun

If you're familiar with logistic regression and need the SAS details these are good references:
UCLA, their annotated output is useful though a bit out of date:
And of course the documentation:
Read up on the class statement and how it dummy code/effect code variables as this is a common source of errors.
Search logistic regression on lexjansen.com for many relevant papers.
My biggest suggestion is to find a set of data/analysis and figure out how to replicate it in SAS before doing your actual analysis on your data. It will save you many mistakes.
