Here are the people you can talk to:
Eric Reynolds and Jacq Cohen work for Seattle's beloved Fantagraphics Books. Reynolds is Associate Publisher, and Jacq is their publicist (she's also worked for Dark Horse comics, so maybe she could answer your what-does-Eric-Powell-smell-like-in-real-life-questions, too). Any questions about the history of Fantagraphics or the best new cartoonists you haven't heard about should go to them.
Matthew Southworth is a local artist who works on the awesome Portland-set detective series Stumptown. He'd be a great person to ask about drawing from real life and photographic research, among other things.
And Tony Millionaire is a famous alcohol aficionado who also draws a comic strip called Maakies, which you may have accidentally read while perusing the ads in the back of The Stranger.
You can ask these people questions individually, or you can hit them all up at once with your general comic-book questions. Go to it.
