Well...I just went through this (I signed up to hubpages about 12 days ago, and started getting adsense a few days ago)...and what I would recommend is getting the amazon id to get into the ad program to make some money through clicks. That's really where I generate my money (we're talking pennies here)...and pretty much wasted 200 clicks already because I waited to write 10 featured articles for higher chance to be accepted by google adsense (which took a few hours--but since it takes some people days to weeks..I think having 10 featured articles definitely had something to do with getting accepted quicker)....
Basically: enroll for amazon id - you need this or google adsense to make money from page clicks (I'm not sure what the process is, but in the earnings section, it should guide you): this link might work for you:
but yeah...do that instead of waiting for a few weeks and loosing out on some clicks.
Then you can add google adsense after you write 10 featured articles.
As someone who literally just went through the process..that would be my recommendation.
