Healing stream still stacks (tested last night). Mana is supposed to stack, but I didn't really delve too deeply into testing it, since I didn't really mess with my scrolling combat text to show mana.

And on the class make up, you can't beat 5 shaman for instant damage output. I know that particular composition is the most popular, but that is the reason. Insane instant damage (pve and pvp, you can't imagine the 'lols' I get when I one shot somebody in AV). Even as mediocre geared as my team is, I still put out respectable damage. Five fire nova totems kill any group where AoE is needed in an instance, 5 grounding totems means no spell will touch you while you burn a group down, and 5 tremors mean any fear lasts less than a second. That's not to mention the 5 tanks-on-a-stick and 2 minutes later 5 fire elementals. I'm slowly getting geared, and have no problem with same-level pulls in instances.
I can confirm mana spring stacking in 5 mans, haven't tested across raid groups.
