Well, if they're dependencies then they'll install automagically, if 
they're related to a program or two (like php-gd is related to php and gd) 
then the convention is usually of the a-b or b-a format.  The rest is 
usually a matter of installing entire package groups (yum groupinstall) or 
knowing the package name (a little black magic - but then you can guess 
and use "yum info packagename" for info, or even "yum info" for 
everything)

yum list installed

or

rpm -qa

"yum list" lists installable packages in the repositories currently 
enabled.
