The fact that your traffic and rankings hasn't suffered lends some confirmation to my suspicions that the recent TBPR drops were only to the toolbar and not to the internal metrics... for now anyway.

So from a traffic and ranking perspective there doesn't appear to be anything to concern yourself about... for now. If indeed this is the reason, there's nothing to say that Google won't apply the "drop" in ways that can affect your rankings in the future. Depends upon how much traffic you get from your Google rankings as to whether or not it's an issue.

From an advertising perspective, if your advertisers were purchasing their spots strictly for the TBPR, then they'll quite likely be less inclined to do so going forward. If you add the "nofollow" tag to all the paid advertisements to get your TBPR back, same thing holds true... if your advertisers were simply after "the green" they'll likely not be interested.
