Documentation/sysctl/vm.txt is linux source tree explains swappiness:
715 ==============================================================
716
717 swappiness
718
719 This control is used to define how aggressive the kernel will swap
720 memory pages. Higher values will increase agressiveness, lower values
721 decrease the amount of swap. A value of 0 instructs the kernel not to
722 initiate swap until the amount of free and file-backed pages is less
723 than the high water mark in a zone.
724
725 The default value is 60.
726
727 ==============================================================
It's easy to find docs on other parameters just by grepping.
