If you're working from Word documents with Word styles already set up, you can place the word document and map the Word styles to existing InDesign styles for a clean import .
Use them, and use them a lot. Also note that styles can inherit from other styles: so you can update multiple styles at once as well as multiple blocks of text. There's also a lot of nice advanced stuff particularly in InDesign that can be done with styles, particularly with paragraph styles, such as using them to auto-generate tables of contents and setting formulas (grep/regex) to automatically apply styles to certain patterns of text. It's worth doing some research on.
There are lots of other features based on the same principle of set a style once, then update all its instances at once. There are Table and Cell Styles for InDesign tables, and Graphic Styles (Illustrator) and Object Styles (InDesign) which is a similar idea for saving fill, stroke effects and other such effects for graphic images / frames. There are also Illustrator Symbols which are whole graphics where each instance can be edited as one.
In illustrator CS5 (under MacOSX) you can go to the menu tab Help and do a search on "Paragraph Styles" ... open it and edit as you wish.
