Hey there "breaking the rules",
Since this thread started way back in 2006, I've made a few upgrades, for instance, taking Augie's advice, I shelved the 3 man dome tent for the single pup, which is pretty spacious inside, and takes up half the room when loaded on the bike.
I found your
Therm-a-Rest link, there are 5 models rec'd for camping:

I have one of those heavier plastic swimming pool types now, $8 at Gen.Dollar. It's the transparent type, with the pockets in it, requiring less air.
The parachute material hammock, that packs into a can-o-beans sized stuff-sack is next on the want list- especially for summer travel. Your suggestion will follow that purchase, I like the dimensions of the Therm-a-Rest.
There is a huge difference in summer and winter prep, especially camping/sleeping.
On that NC trip last April, I didn't take the air mattress, had the kindergarden sleeping pad stashed behind the seat. Because I was carrying extra clothes, I could lay the extras under that mat, to get the inch of comfort.
Part of the trick is to make things
Dual-Use, the vinyl bag becomes the tent's welcome mat, along with a 2x3 piece of tarp material, rolled up during the ride. In camp its a place to stand in the dew-dropped morning and not get your socks wet.
Since I quit carrying books, use the newspaper for entertainment at night, you can also wad up a lot of pages to augment your pillow, then dispose of it in the morning.
Also on the NC trip was the 1st time I used the super-sized zip-lock bags (10 per box, $3). One zip-bag could fit both fleece blankets, squeeze out the air, and stuff it into a vinyl bag, then put it in the front basket.
Those bulky, but light weight items, were perfect for the front basket, while the heavier stuff rode better behind me in the saddle bags.
Another dual use item is one of those nylon laundry bags. If you have to camp in swampy conditions, spray on some OFF, put the bag over your head, & it will keep the huge dragon beetles out of your nostrils or ears.
Things that have worked well, imho:
No denim jeans.
Shower flip flops for camp shoes.
Few extra batteries, buy more as needed along the way. (The old camera took 4, the new lighter Fiji only takes 2). In fact, avoid any appliance that takes 4 batteries (e.g. large flashlight).
Every 3 days, take off a half day to rinse out the dust, maybe do basic laundry by the stream, enjoy the hammock.
Start collecting half used items, like half a bottle of Deet mosquito spray, half stick of deodorant, half tube of toothpaste. All those little ounces add up in the toilet kit, and you only need a weeks supply of toilet paper, not a huge roll.
There are still tools I've never used on the road, but that little black umbrella bag is the best .50 cents I spent. If it doesn't fit in there, it ain't going with me. 3 box wrenches, adjustable needle-nose, the allen's - pocket set, scissors, 6-1 screwdriver, etc).
I want one of those US Air Force- Swiss Knifeyish combos, it even strips wire.
I'm a big ChuckTaylor All-Star fan on shoes, and Goodwill for quick in-out T-shirt replacements, which cost less than a laundrymat PLUS soap powders.
