Not being a Copic guru myself, and having taught myself color theory from books, a lot of what I've learned about rendering comes
from a whole lot of trial and error. I know a lot of my readers are interested in Copic marker rendering, but may not know where to find reliable resources. For this post, I've compiled the online resources I've found in hopes that it makes learning to render with Copics easier for you guys.
Coloring, "Manga-style": Tends to rely on coloring only within the same color family, generally starts dark and goes lighter. This isn't always true. Tends to have that watercolorish, washed out look.
A good basic primer: http://yiji.deviantart.com/art/Yiji-s-Complete-Copic-Tutorial-31743361
Note: A lot of these artists work from dark to light, I work from light to dark.

Using marker papers with your Copics: http://ilikemarkers.blogspot.com/2008/07/alcohol-marker-papers.html
Feather blending, a technique I still have a lot of trouble with: http://ilikemarkers.blogspot.com/2008/07/feather-blending.html
An ounce of prevention- What will ruin Copic markers: http://ilikemarkers.blogspot.com/2008/07/feather-blending.html
Actual marker paper allows you to blend better as the marker may remain wet longer, but I prefer plate, because I don't like that super slick blending for my own work.
I only have problems like this when I use anything other than plate Bristol, but with Plate, I have to let my lineart dry overnight or it will smudge: http://ilikemarkers.blogspot.com/2008/06/basic-coloring-troubleshooting.html
