Hey there, Private.
Welcome to the VE. What you should do first in order to begin your training is head over to the StormTrooper Academy and post a new topic saying that you are reporting for duty. Then, the Commander of Training, Yillis, will post on your topic giving you instructions on how to begin your training.
It's loads of fun here. And, if you need any extra help, drop by the IRC chat, or even send a Private Message over the ComNet to any body who you think could help you out.
Good luck, Private!
