One of the best ways to learn the ins/outs of PvP on your shard is to get in touch with a guild that PvPs on your shard. They will be able to help you get set up, teach you common tactics (potions, trap boxes, etc...), and give you opportunity to practice.
Simply going to a Felucca ruleset will be very discouraging, as you will be highly unprepared for the encounter.
You may want to try getting in touch with a guild by using the shard specific forums here on stratics. There are plenty of guilds out there with good people to help you out. Your PvP experiences will be highly influenced by the company you keep.
