Hi Degx  Welcome to GW2.

As JDP stated that build may or may not be "good" any longer.  ANet is currently in the middle of changing all of the classes and I would expect to see those changes right up until release.  I would encourage you to jump into the game during Beta Weekend 3, July 20-22 and try out many different classes.  Through play you make find a class that you like a lot more than Ranger.
A lot of people can tell you that they are going to play a totally different class than what they first thought.

But Ranger is a very fun intuitive class that can play many roles and require many different levels of skill management.

I would recommend the Wiki: http://wiki.guildwar.../wiki/Main_Page

And reading the threads here.  There are several good posters in this forum that already have some good knowledge of the GW2 Ranger.
