Answer 1

There is no direct support for shared affiliation addresses in the sig-alternate class. Basically, ACM suggest you to give all information for each author in a dedicated \alignauthor block.

\documentclass{sig-alternate}

If you don't like this or consider it as too space-consuming, you can of course hack around this manually to get the intended result. This is probably not "correct", but I have to admit that I do this for space reasons quite frequently – and nobody ever has complained about it.
