we are going to try some testing with our ads and some custom tracking, but obviously dont want to click our own ads a bunch of times, and rack up our clicks.
i know, i want the world in a handbasket.

for multiple words, use KEYWORD1+KEYWORD2 (etc.)
The adtest=on parameter should keep you from being charged.
If the ad preview tool doesn't work for you...
You could create some random terms (like company name + your name or some other random word) with a lower CPC bid (<$0.05) and "test" them. This way you won't rack up very much $ during your testing.
I don't know if it'll fit within the testing you're doing, but you could try to find your ads in the 'Search Sponsored Links' function at [google.com...] ... You'll not be charged for the clicks. See [adwords.google.com...] for more details.
