OP first thing...welcome to guild wars!
2nd thing, sorry there are no GMs online (and the few that are are not there to help you in any way)......
ok, getting to your issues...
the few helpful posts here have said there is an L menu with your quests listed, you NEED to do the primary quests, you CAN do the others (most of which at your point in the story will get you some extra skills and some xp)...for a list of the quests you need to do try this link

(and you are a prophecies born character)....so the next quest you should be doing in the Krytan ambassador which can be gotten from capt orsic in ascalon city. Since you played thru pre-searing (the nice green area before the 2 year break) you will know about the ! above people's heads indicating a quest person......there are quite a few of them in ascalon when you arrived, you can take all of the quests (you are not required to do them all just the primary ones)....and do them as you like.
I hope this helps, I know playing by yourself at the beginning can be very confusing...you might also want to find a guild ---there are many out there that are will to help you along as well as help you with your gaming issues too.
