Best Place to Learn Adwords?

I figured it's the Adwords tutorial or learning center itself and through just using Adwords, but thought I would ask just in case.

I just signed up, made my first Ad which would direct to a squeeze page which was to teach people how to make money online. HOLY CRAP! I put my campaign on pause with just that one ad, went out for a couple of hours figuring I'd tweak it when I came back, and when I returned I had 3 emails from Adwords which went from "your ad has been disapproved" to "your ad violates our TOS" to finally "we'll suspend you if you don't fix it". Wow I hate to think what would've happened if I let it go for another hour or so.

So I have an informative website which teaches people how to make money online, lots of great content, but I use a separate URL with the express purpose of capturing emails - this is the squeeze page - so I don't know if they would or wouldn't take issue if I directed people to the same video but on my legitimate informative website page which still has a sign up form for the same mailing list but obviously that site has lots of other content on it. Would that be better?

Thoughts?
