Am I right that pagead2.googlesyndication.com stands for clicks generated from the content ads in google adwords?
Yes, you are right.
Also, in the log files what do the 'search partners' and regular 'google search' entries look like?
The referrers are the same as from natural SERPs. If you want to distinguish the AdWords clicks through, you have to modify your destination URL in any way (e.g. by appending a unique query string).
[example.com...]
so any traffic coming from that campaign would land on a unique, identifiable page.
