Are you in school? Get an independent study going with a professor on a topic she likes and you wouldn't mind learning. Emphasize that you want to get your training wheels for autodidactic math education.

One caveat is that many of these textbooks do not come with a solutions manual. So, in terms of practice, I think that's where the dearth of uploaded lecture materials could come in. Sometimes, there might be no e-learning/opencourseware material for the topic you're interested in. In such cases, I found that if you look through universities' Websites closely enough, professors upload a lot of course materials on their personal pages. You can do this by finding a random university's math dept. page, then searching from course/faculty listings.
Last of all, I'm pretty certain you've heard of this site already, as it's being circulated quite a lot lately, but many have professed that videos from khanacademy.org to be quite helpful when grasping basic mathematical concepts.
