Also, M-x apropos-variable is very useful once you know the prefix
used in a package e.g. dired-

I also find it useful to try M-x customize-group <ret> dired to see
all the customizable variables in a package like dired. 

Many packages with info pages will also include an index of functions
and variables. 

and of course, as aptly mentioned already by Lukas and with a less
than subtle reference to 20th century pop culture 

Use the source Luke!
