Jun 24, 2011 at 1:38 comment added Greg Friedman This is maybe not what you want, but there are some very good introductions to derived categories available now. The first coming to mind are Gelfand-Manin, Methods of Homological Algebra; Dimca, Sheaves in Topology; sections of Borel's book on Intersection Cohomology; and Banagl, Topological Invariants of Stratified Spaces. Admittedly these show off my topological bias. If you're daring, there's also Kashiwara-Schapira. I think David Massey also has some lecture notes.

Jun 23, 2011 at 20:54 comment added DamienC I do really mean $F$, because I ma working with the derived category of $F$-modules (as in the wiki). But you can just take $F=\mathbb{Z}$ if you like.
Jun 23, 2011 at 20:40 comment added James D. Taylor Thanks! You mean $[S[-k],S]$, right? Because $H^k(X,S)$ doesn't depend on $F$.
Jun 23, 2011 at 20:37 comment added DamienC Very shortly, for any sheaf $S$ (i.e. a complex of sheaves concentrated in degree $0$), $[F[-k],S]=H^k(X,S)$.
Jun 23, 2011 at 20:30 comment added James D. Taylor Why is $[F,F[k]]=H^k(X,F)$?
Jun 23, 2011 at 20:27 comment added DamienC I guess that there is a typo and that $[F,X[k]]$ should be understood as $[F,F[k]]$.
