You can change the text after the? for each ad that you create, and get full tracking of various ads. This has worked well for me so far.
The only issue is the "ref_g1" tag (or whatever you use) shows up in the browser address bar when the user visits the site, something I would like to eliminate, but I don't think that is possible.
I'm not sure if this helps, but you can get a service like ConversionRuler, which will show you exactly how many visitors you've received from AdWords. There's some simple setup needed (the time it'll take you depends on how many keywords you've got up and running, and how many parameters you'd like ConversionRuler to track).
BTW, I'm NOT a ConversionRuler rep... just have been using their system for a while.
Cheers,
