Normally you use yum for doing so. <http://centos.org/docs/5/html/yum> should
contain enough info.

You can't except if you build these also as RPMs. And rebuild every other RPM
which depends on those against the newly built RPMs.

CentOS is not and never was about the latest and greatest. CentOS is about
having a stable set of packages which do *not* change over the lifetime of
the product (with a few exceptions). Security fixes are backported into these
versions. More info about that can be found on http://wiki.centos.org/

No, because those will get overwritten on updates.

Same for RPM.

/usr/bin only when installed by the package manager. /usr/local/bin for
selfcompiled packages, /opt/ for binary packages. man hier(7)

Yes. Bad idea and it *will* screw up your system. Read up on CentOS and try
to understand why we ship exactly that set of packages contained in any
of the 4 available CentOS versions. If you find that not having the newest
software available, CentOS might not be the correct distribution for you.
If you want to have a stable set of packages supported for seven years(!),
then stay with CentOS. Mixing CentOS packages and "stuff from the web" will
not help with that.
