Welcome to the vast universe of Star Wars.
You might want to check out Wookieepedia, it has pretty much everything about Star Wars on there.
However, that being said.... Star Wars is an interesting universe, in the sense that it's lore *cannot* be learned in a matter of hours, days, or weeks. Your knowledge here is accumulated over months and years.
If you're that interested, watch the movies, play the games, read the books, and research on Wookieepedia.
Then, you have my permission to roleplay.
