How to change the place where IDEA stores stuff?

Problem : Your home disk is full, and IDEA keeps filling it with cache and LVCS info.
Solution : change the idea.system.path property

How to : In the file /bin/idea.lax, edit the -Didea.system.path property to a suitable value. 

default value :
    bin/idea.lax="~\\.IntelliJIdea\\system" 
   
after :
    bin/idea.lax="D:\\bigDisk\\idea\\system"

on Mac OS X use /Developer/bin/PropertyListEditor to edit Info.plist in the Idea.app binary

What are modules and why would I want to use them?

Modules are subprojects, if that helps. You can create a number of modules, each of which has it's own classpath, sourcepath, libraries, etc. You can reuse modules in multiple projects and you can specify dependencies between them. When you use them, they show up in the project tree and you can edit code in them in place (i.e. without having to open a separate project); IDEA will know to recompile only modules that depend on the module you change. If you add a library to a module in one project, the change is visible to all projects which use it.

You can also have different types of module. For example, you can have a type of module which represents a group of EJBs, another type which represents a web application, and so on. These can be made to automatically regenerate EJB JARs, WARS, EARS, etc. for you each time the module is rebuilt.
