I built a stitch and glue canoe a while back, it's a pretty simple process. Just take your time. Cutting out the panels accurately makes it easier down the track.
I got most of my supplies from
http://boatcraft.com.au/, and found them very helpful. Jem watercraft
http://www.jemwatercraft.com/ also has some good information, which is where I got the plans for the canoe.
Like DaveB I also have the Cirrus plans and will get to that eventually.
Good luck.
