The recommended way to install software is using a yum or at least rpm. 
The further you stray from core CentOS packages installed the CentOS 
way, the more likely you will get stuck with a broken system that this 
list or the forums will find difficult to support. That said, there are 
some good repos out there including dag.wieers.com and EPEL.

The versions used in CentOS are derived directly from the upstream 
product. This is an enterprise distro after all, stability is valued 
more highly that being on the bleeding edge. But yes, old versions of 
PHP and PostgreSQL can be problematic when something like the latest 
Drupal (7) requires PHP5.2, and PostgreSQL 8.3 is way better than 8.1.
It is possible to upgrade these but not possible to describe how to do 
it here. Google can help.

Software should be installed wherever the RPM wants to put it. It is all 
about maintaining a stable, reliable system in a known state.
