Give it another few tries, I also found BRC pretty rough at level 80 with my melee team but it got far easier with a bit of practice. The 2nd boss is definitely the worst, especially on heroic mode, but you can actually skip her if you want to by clearing to the bridge, exiting the instance and re-entering (a portal to the third boss will be to your left). You might want to avoid Throne of the tides for now, but when you hit level 83 give Vortex Pinnacle a shot (very easy for melee)

Another thing you may want to consider is running dual healer's since you have the classes to make it possible. When I hit 85 I tried to start on Heroics right away and found them pretty tough, some were definitly doable with 1 healer but double healer made them so much more comfortable (I used Resto Shaman + Holy Paladin).

If you decide to give questing a shot, there is no reputation associated with the water world so you can just skip it all together (I did).
