Get a head net - I used one in Siberia against the mossies (they're big out there) and in Australia against flies (also bloomin' big). Essential if you're camping on a still night.
For sun-cream, have a look at
www.greenpeople.com (or .co.uk - can't remember). We used their stuff in Australia and didn't burn once even though we were cycling right through all the deserts. It's all organic and good stuff. Have a look at
www.red-line.moonfruit.com for touring pics.
