Concerning smooth infinitesimal analysis, I have pointed FOM readers
before to the book on the subject by JL Bell:
John L. Bell, A Primer of Infinitesimal Analysis, Cambridge
University Press, 1998.
There is perhaps no better place to go than the Introduction of this
book for a non-technical summary of the theory. More immediately to
hand (or to mouse) are two preprints that Bell has written:
An Invitation to Smooth Infinitesimal Analysis.
http://publish.uwo.ca/~jbell/invitation%20to%20SIA.pdf
Infinitesimals and the Continuum.
http://publish.uwo.ca/~jbell/New%20lecture%20on%20infinitesimals.pdf
