Good lack to you but this is very bad advice. It is too much even for average
mathematician.
As a serious first read for CS guy I would recommend Categories for Types by Roy Crole.
For short introduction: Basic Category Theory for Computer Scientists by Benjamin Pierce.

The problem with learning CT lies in the large amount of mathematical intuition that is
assumed. This intuition can be build by studing topology and algebra. Learning CT without
this background is kind of a Turing test;-)
