One other piece of advice: If you do decide you want to trying buying at an auction, go to several auctions before the one you're interested in. See how they're conducted. See how many people turn up, and whether they seem to be like you, or whether they're investors. Just get a feel for it.
Finally, while you can find some good deals at auctions, you can also find some good deals on the MLS. And you can find some on your own, not listed at all. So, while it's fine to focus on auctions, recognize that they're not the single path to the great real estate deal.
