Welcome! I too converted from blackberry and it was quite an adjustment for me. For one, battery life, notifications, and push email are not quite the same. Other than that, I love android. I haven't gone through this but check out the link.
I converted myself. For me, the biggest thing was getting used to the touch keyboard. The best piece of advice I can give you is just type as much as you can for a few weeks. Even if you prefer doing it on a computer, whatever, do it on your phone to get used to it.
Also try out many of the alternative keyboards, like Swiftkey 3 and Swype.
