If you look in the Travel Products forum, there should be plenty of info/advice for the issues.

You should definitely move away from cotton clothing. When traveling, I usually bring clothing made of very light synthetic or wool material. These are generally designed for travel or exercise and dry very quickly. They can be found in t-shirts, polo shirts, underwear, and socks. Additionally, when you wash them (I just do it in the sink), make sure you wring them out in a bath towel, which will absorb most of the remaining water. It then dries very quickly (a couple of hours). As for pants, I sometimes bring jeans but don't expect to wash them and have other pants as well. I typically travel in the winter so it's not generally an issue.
