Honestly, the best way for you to get gear and level up at the same time is to join someones DC run (Decaying Crypt MP10). Yes, you will feel squishy. but you will blaze through the paragon system and get good drops. Make sure you research what a DC run is before jumping into one (you can Piss off the preppers if you F-up) I would allow you to drop in but I'm on US server. Just a heads up, when you join MP10 farming No one will res you. It takes too long and there is a high probability of them dying in the process.
I can probably even budget build your set for you. But, server and time zone issues.
Also, you can either WW/rend or HotA. Either way they are all the same builds. Why? Because all current Barb builds rely on WoTB and Battle Rage. So enjoy "Thrive on Chaos" while you can.
