When I used the link my anti virus didnt detect anything just received the in game mail and done. Could have possibly been a hack attempt but not 100% sure.

Once you start on the beginners world the game will pretty much tell you where to go next. Just follow the story line and you will be fine. Once you hit in the 50s you can move on to the expansions if you like.

Honestly what you do is ignore everything but the beginning story. There is a vendor on fleet that sells a token to remove all bonus exp get that and just enjoy the game. With level scaling you can see all the old content and hit level cap before you have to worry about the expansions.

Getting your comp up is easy now though. But like they said above I would shoot for 50.
