Yeah, as has been said, as far as shoes go I'd recommend the small, light water-resistant type of boot that's comfortable in the sole. If you're buying them new, make sure to wear them around enough to break them in before you leave. For socks, I'd recommend thick alpaca socks that are designed for hiking (breathable and comfortable). Thanks to the above combination, I had no blisters after a two day thirty-two mile hike through the deserts of Wyoming, when most other people did.
Long sleeve shirts would probably be best, and simple cotton-polyester blends have always worked well for me.
I'd also recommend treating your clothes with
Permethrin before you go; it really helps keep the bugs away.
Don't forget sunglasses, and hats that shade all sides of your head (the back of your neck, in particular).
Lastly, it's probably already evident, but make sure no one in your family wears boxers or any other form of loose undergarment. Boxers can become quite painful after a lot of walking.
Jam it back in, in the dark.
