That is a good way to start, for other opportunities, keep an eye on the "Work for CP's" forum, or watch the Sim News, and maybe when you get more used to the game, join an SWC Team.
Join a faction. 9/10 will send a pilot to pick you up, which will enable you to get started on your playing life in this game. Just be aware that the game works on delayed-action-timer (Meaning it takes longer to do actions here than it would in real life!).
The Bug Tracker (Mantis), is an external piece of kit that we use to keep track of bugs within the game, as users report them. You need to create a separate account there (Best being your handle), and then report the bug.
Helping you, I've done the best I could within the short time-frame I had free to answer your questions, but due to me being a member of the administration, I cannot offer you any In Character Help.
Simple, buy and sell things through the commerce forum and CenterPoint. You'll probably find you trade with some people a lot, and eventually you will be happy and both of you will be happy to send first to each other. Then as that grows and you get known as a fair trader etc, some of your friends might ask you to middle for them. After that, you'll slowly build up a history as a fair trader and a good middle. It will take years and years.
