If you would like to register as a seller. There is information on the site that displays links to go to this. If you check the bottom of the screen you can see there are little links and look for the link that say "Become A Seller". Also, if you are still confused, don't be afraid to contact customer service and ask them! They would be more than happy to guide you to the right direction when it comes to becoming a seller:) I hope this help!
Just study and understand from technical specifications if it corresponds to what you are looking for and chat with seller if needed. Also be polite to sellers and exercise patient during your transaction. On losing your money: Alibaba has platforms to report any dissatisfaction and have buyer protection services which i will recommend you read Alibaba protection policies.
