Everybody has their own opinions, but I don't really agree with some of the others here.
I'd say a seller is in good shape with roughly 10 positive feedbacks. Of course, the more the better, but once you have 10, the quality of your listing and feedback speaks for itself.
Because eBay has fraud insurance, people are quite trusting of the eBay marketplace. Contrast this to Anandtech For Sale forum, where newbie sellers are expected to ship first. With eBay auctions, the buyer always pays first. I'm not saying what's better, just how it is.
First off, yellowperil's advice has two problems. A) Buyers generally won't get involved in auctions with high opening bids. B) A high opening bid means higher fees. I don't recommend this strategy at all. However, if nobody bids on the auction, then you can relist it for free, so it's not a total loss. It does make sure you get close to the selling price you want.
Secondly, PayPal is fine. Make sure you ship only to a confirmed address. If you want PayPal fraud protection, you'll need a premiere account, but I'm not sure this is worth it (PayPal isn't known for actually providing customer service). A premiere account is required for receiving credit card payments, but the fees will add up quickly. If you plan on regularly selling on eBay (as a hobby), I'd suggest keeping one personal and one premiere account. Buyers get a little confused with this strategy though. PayPal has its problems, but 99% of users don't have any horror stories.
As far as listing items at 1 cent, this is neither good nor bad. I definitely believe in bidding "action" but if you start off a premium item at a penny, it just results in a lot of meaningless early bidding. Also remember that most of the action in an auction is in the last 24 hours. So don't be discouraged if the first several days look bleak. As a general rule, I like the opening bid to be about 1/3 of my target selling price, although I will go lower to reduce listing fees.
Although I don't like reserve auctions, I am using them a bit more recently because they "pin" the Buy it Now option. If you don't set a reserve, any bid will remove the BIN option.
Finally, take all this advice and carefully scrutinize the fees page for both eBay and PayPal. You'll come to see that fees are your main enemy. The eBay marketplace is very healthy (eBay is a de facto monopoly), but the fees really add up quickly. psteng19 does have some good pointers to follow.
Note I'm not saying my advice is better than anyone elses; just some differing opinions based on experience. Good luck.
