website Optimization

[imperialis]

I have used the website optimization site and could someone explain how I fix these things

TOTAL_HTML - Congratulations, the total number of HTML files on this page (including the main HTML file) is 1 which most browsers can multithread. Minimizing HTTP requests is key for web site optimization.
TOTAL_OBJECTS - Warning! The total number of objects on this page is 22 - consider reducing this to a more reasonable number. Combine, refine, and optimize your external objects. Replace graphic rollovers with CSS rollovers to speed display and minimize HTTP requests.
TOTAL_IMAGES - Warning! The total number of images on this page is 18 , consider reducing this to a more reasonable number. Combine, refine, and optimize your graphics. Replace graphic rollovers with CSS rollovers to speed display and minimize HTTP requests.
TOTAL_CSS - Caution. The total number of external CSS files on this page is 3 , consider reducing this to a more reasonable number. Combine, refine, and optimize your external CSS files. Ideally you should have one (or even embed CSS for high-traffic pages) on your pages.
TOTAL_SIZE - Warning! The total size of this page is 217518 bytes, which will load in 47.75 seconds on a 56Kbps modem. Consider reducing total page size to less than 30K to achieve sub eight second response times on 56K connections. Pages over 100K exceed most attention thresholds at 56Kbps, even with feedback. Consider contacting us about our optimization services.
HTML_SIZE - Congratulations, the total size of this HTML file is 4063 bytes, which less than 20K. Assuming that you specify the HEIGHT and WIDTH of your images, this size allows your page to display content in well under 8 seconds, the average time users are willing to wait for a page to display without feedback.
IMAGES_SIZE - Warning! The total size of your images is 198828 bytes, which is over 30K. Consider optimizing your images for size, combining them, and replacing graphic rollovers with CSS.
CSS_SIZE - Warning! The total size of your external CSS is 14627 bytes, which is over 8K. Consider optimizing your CSS for size by eliminating whitespace, using shorthand notation, and combining multiple CSS files where appropriate.
MULTIM_SIZE - Congratulations, the total size of all your external multimedia files is 0 bytes, which is less than 4K.

Some of your product small images are 50k+ make them smaller in byte size

Some of your background images are too large in bytes

How do I make the css smaller without killing it

It seems that every time you add a mod, you also add a new style sheet. Is it possible to combine all those different CSS files into one big gynormous css file?

I wouldn't worry much about the size of the CSS file. Your images are what's slowing down your site.

You can merge stylesheets, but you pretty much have to go through line by line to make sure you don't overwrite an id or class that you don't want to. I'm not sure it's worth the trouble.
