To the first question: No Rockbiter does not stack with these, or any other weapon buffs. They all overwrite eachother. Easiest way to put it is: You can only have one buff on your weapon at a time be it from items or spells. (you may also have an enchantment)
Specializations:
As a shaman, you really CAN go all three ways. Currently, I am specialized to get Flurry and the windfury totem upgrades with lightning shield, 2 hand maces and axes, ghost wolf, and the above all maxed. I am now working on elemental magic. (I previously had clear casting, and it IS AWESOME, but I respecced to do heavy melee damage. For info on why I chose melee, and what I do with my melee, check my reply to this thread
here.
I expect I will probably redo my specs many many times until I find what I want. I am a PVP shaman and as such I am really leaving the healing tree alone at the moment. WHo knows, I may go all out into that tree someday though.
Hope this helps some.
