I totally agree. Being prepared with good, comfortable clothing and shelter is essential not only for enjoyment, but also for real survival.
I like to where sock liners - to wick the sweat away from my foot, and then have a cotten/polyester blend on the outside. Same thing with my undershirt: rayon or nylon undershirt, with a polly/cotten outer, then cover with a light sweater and wind-breaking shell.
In addition to your clothing comments - I recommend people try a hammock tent or chair and see if they like it.
Hammock tents and shelters have come a long way in providing small, lightweight comfort and effectiveness, especially in bad weather and hillside terrain, where a tent could not be setup.
One product you have to check out is the Amazing Wilderness Camp Chair, at
http://www.canada-camps.ca they have videos to show you how to build one, or you can buy one off their web site.
There are also a bunch of videos on hammock tenting and shelters.
Enjoy camping in Canada!
