Some references:

The book by A. Borel "Algebraic D-modules" contains much of what will be covered in the first half of the course.

The book by Kashiwara "D-modules and microlocal calculus" emphasizes the role of b-functions.

Malgrange's Bourbaki talk from 1977/78 (LNM 710) gives a nice explanation of microlocalization and involutivity of the singular support.

Bersntein's notes is a very good, albeit concise, exposition of the key results including application to Kazhdan-Lusztig conjectures.

A course by J.-P.Schneiders explains some of the basic constructions.

A recent book "D-modules, perverse sheaves and representation theory" by Hotta, Takeuchi and Kashiwara touches upon most of the topics of the course.

Ben-Zvi's page contains further links. By the way, his paper with Nevins (JAMS 17 (2004) 155-179) shows that various definitions of D-modules agree sometimes even for singular varieties.

In the discussion of Kazhdan-Lusztig conjectures I followed MacPherson's argument described in the Bourbaki talk Quelques applications de la cohomologie d'intersection by T. Springer. See also Soergel's ICM (1994) talk "Gradings on representation categories" for a discussion of grading on categories and its relation to Kazhdan-Lusztig conjectures.

The definition of unipotent nearby cycles was introduced in Beilinson's paper who to glue perverse sheaves, a typed version can be found here.

A discussion of b-functions and multiplier ideals appears in recent papers of Budur and Budur, Saito.
