I don't usually weigh in on these topics, but I figured I would.
I mainly play PvE, but when I saw the GOB was needed for a legendary, I knew I have to get into WvW. I started by doing the tasks listed before. My build was not very good even by PvE standards, but I kept at it. Before long, I joined a zerg and then went around taking camps and towers. Before long I had completed the track. Having boosters did help.
The problem... I started to enjoy it! I got killed a lot by the enemy. Curse those on Crystal Desert and Northern Shiverpeaks. Not I am working towards creating a WvW character, a Scourge. And even joined a WvW guild on Darkhaven. I have blast and meet some nice people who are more than willing to help out those newbs who have been playing the game since release.
