You don't want -m64 on i386. Why don't you switch to the amd64
architecture, where you get at least some of these optimizations by default?

Depends on the program, I think. In general, -O3 produces bigger
binaries (than -O2) that may or may not run faster. Mozilla even
builds with -Os by default.

With recent dpkg versions (1.15.7 and newer) have a look at
dpkg-buildflags(1).
