I downloaded firebug and yslow.  They are incredibly useful, as is the 
websiteoptimization site.  Where and why I am with this?  I have several 
clients for whom I have set up with Joomla CMS and the Virtuemart 
eCommerce component and one of the various template systems offered for 
Joomla.  The basic joomla structure includes a triad of CSS, JavaScript, 
etc files along with test.  The template system which we like comes with 
a ton of addons, some of which can be disabled through if/else tests, 
setting whatever to false, etc.  This all compiles and it now becomes a 
Cadillac with chrome hood ornaments. 

The task at hand is to take the Cadillac, strip off the excess baggage 
and deliver an aerodynamic solution.  It takes many hours to test, 
merge, delete unnecessary components but is worth it from my 
perspective.  With some minor theme customization the 600K Caddy is now 
an <250K Renault.  The goal is to get to somewhere around 150k.  I am 
systematically taking the many CSS files and combining them to one (also 
with a couple IE bug fix variations), then later to remove unnecessary 
white space, all the while documenting the process, steps so that future 
changes are doable.

With this particular template system they provide theme (color) 
variations with a default set of background images as well as custom 
versions based upon color.  In essence I think it's an incredibly smart 
way to deliver options, but yet provides extraneous images which also 
need to be uniqued.
