My personal experiences with eBay have been with selling stuff I find hitting garage sales, nothing better than buying a Ralph Lauren Polo shirt from some suburban wonk for $1 and reselling it as a vintage RL Polo shirt (which it was) to some dude in Germany for $22.00 plus another $15 for USPS Global Priority Mail.
I've been slowly cleaning out my closets, selling tech hardware from special projects collecting dust, I'm seriously considering attending the eBay Live in San Jose in 2005 as I want to start selling higher ticket items than I am now.
Now my advice to you is the same advice I gave my sister, sell what you know, sell what you can buy cheap and sell high, treat your buyers as if they were in your own store, offer them shipping plans you can deliver on, accept Paypal only, and leave glowing feedback.
Follow that and the feedback will roll on in, like porn, they will bookmark your eBay ID or store and buy from you, recommend your wares to their friends and family.
Hope this helps!
