I think you'll have to stick with tags, just make sure you use
exuberant-ctags, it has much more fancy support for things. A solution
based on semantic is possible, but not available as of yet.

See semantic-idle-completion-mode, semantic-ia-show-doc, although that
depends on how much info you want. You do get the prototype though.

That's good, since ECB doesn't concern itself with completion :).

Semantic should fit the bill. There's semantic-ia-complete-symbol[-menu],
and also semantic-hover-completion.el, which I'm going to post in a
minute. I'm not exactly sure how much stress the C++ support can stand, as
I don't code C++, but basic testing says it works pretty well.
