how far it gets its going to be related to how people are finding your site, and how much room you have to grow.
if everyone is coming in from search, it depends how many people are searching.
I have a few content sites that drive about $10CPM, but even with #1 organic ranking, I'm limited to about 1500 visitors a month. 95% of my traffic is from search. 99% of my revenue is from people that found my site from search.
generally, as far as adsense goes, the common wisdom is that repeat users do not drive advertising revenue. it's the search hoppers that are the ones that often click on the ads. making the site sticky doesn't necessarily mean more adsense revenue, and here is probably where other advertising mechanisms that require high number of impressions would start to come into play.
affiliate marketing might be something to look into as a supplemental as well, although i'm not sure what that is in your market.
I've got a site that gets ~10,000 uniques per month (www.area51.org), and I still have never found a way to make much money at it. Yes, I've got ads. And yes, I've thought about affiliate marketing. But I wish I could bust out of my boxed thinking and come up with some revenue model that's more compelling.
(On the other hand, the site is self-sustaining; I don't have to think about it much.)
