Mmmm, i don't know that attributes will result in better code, or even faster code though in some situations applying the correct attributes could result in faster code execution. But really they are just information to the compiler know that an action is exptected before this method or class or even project is executed. I suppose they could be distantly related to Pre-Processor directives in c or c++. A real world example of the use of an attribute could be...

<ToolBoxItem(False)> _
Public class SomeClass..

The above attribute would obivously prevent that class from showing up in the toolbox. Most of them are quite friendly in regard to how they have been named and so they're usage should be fairly clear.
You should create your own attribute if there are none that fit your purpose and you wish a custom action to be performed at runtime.
Here's an article that may help.
