Eclipse

Extract eclipse archive in a folder
Edit he file eclipse.ini to set JVM memory arguments. For example, if you have 1Go of RAM, you can set this file to :

-vmargs
-Xms256m
-Xmx512m

And if you have 512Mo of RAM :

-vmargs
-Xms256m
-Xmx384m

It depends on how do you use Eclipse...

Eclipse Tomcat plugin

Unzip plugin in Eclipse plugin directory
From the plugin folder, unzip DevLoader.zip to <CATALINA_HOME>\server\classes
In the plugin you have two readme files to have more details about the installation, or you can see the movie above.
