Hi Cadiliana and welcome to Torn. :)
Torn has a lot to offer and many different paths you can take which means it can be overwhelming to take it all in at first. Don't worry about learning everything right from the start. Most of it you'll pick up as you go along. As long as you get started on a good path, and use the available resources to help guide you in the right direction, you'll have no problems!
I always suggest starting by reading
Baldr's Basic Advice. Following his guide will ensure you have a good start to build upon. Take some time to read some different threads in the
Tutorials & Guides section of the forums. There's an entire wealth of information there. If you've got anything specific you want to learn more about, you can always search for it on the
Torn Wiki.
Last but not least, never be afraid to ask questions if you're unsure of something. Make a post here in Q&A, ask members of your faction that are more experienced, or even message a
Helper, Moderator, or Officer if you just can't figure something out. Torn is full of people who are willing to offer advice as best as they can to help you get going. :)
