[Couple of questions from a newbie]

Ok so I have gotten to mastery rank 1 and I'm using Excalibur I've been in the game for a little under 2 hours total and need some advice I have completed Vor's prize and venus junction, now I'm lost I have no clue where to go or what to do. I'd like to join a decent clan that will help a newbie learn the game, also I'd like to get any other tips, tricks, hints, etc. about what to do next I have no prior experience with this game. Thanks
