I noticed on your blog that you intend to start out with around 10 miles per day at first. This is a great idea, especially if you're not used to walking for distances.
I thru-hiked a 50 mile trail (but turned it into 64) this fall, and while I was used to dayhiking 12 or so miles, I bombed through this trail in three days: 20 miles on day 1, 26 mi. on day 2, and 18mi. on day 3.
I missed a lot. I had 4 days available, but for some reason I felt driven to push myself, and didn't stop to smell the roses. Didn't take many pictures, didn't rest at a really cool waterfall, didn't pause to take in the views. I regret having hiked so fast.
My feet also didn't appreciate it, as they developed 10 blisters.

Practical Backpacking is a good resource, and has a forum called "ParaWilderness™ & Non-Traditional Backpacking" that has information that might be pertinent to your trip. And yeah, if you're near the AT, steer yourself onto it. Actually, since you'll be crossing the PCT, CDT and AT, maybe you could hike a little on each trail as a starting point to the prestigious Triple Crown!
