That's pretty awesome, man.
After starting a novel-writing career, I'm finally dipping my toe in the comic-writing pool myself, though I'm going the straight-to-GN route. I figure I'll start a thread when it's further along, but I'm excited to do it. A friend of mine and I are creating this short series of graphic novels and I wrote the first 13 pages of it today and am loving it. I have an artist set up that I really enjoy and need to find a toner and a letterer, but we'll get to that when we're ready. As much as I prefer color comics, we're going the B&W route for pricing reasons.
Anyhow, just thought I'd mention it since you've been there. Wish me luck.
Also, do you have an estimated time-frame for when you're hoping to release a tpb?
