Welcome to Steemit man! Me, or just about anybody else here are happy to answer any questions you got. Or you could always do a google search. Most of the time, if I'm confused, or ain't sure how to do something, someone has already made a post explaining it.
There are tons of cool tools and things to do on here. A couple of my favorites are Steempeek, a cleaned up, more user friendly interface for Steemit. There's also SteemMonsters. It's a cool trading card game on the steem blockchain. They're always having art contests, which is something you might be interested in.
