More links = more HTTP requests = slower pageload. However you can concatenate your CSS files into one to avoid multiple HTTP requests.
About CSS reset, you have a few options:
– Barbarian style:
– Paladin style: the CSS reset from Eric Meyer resets what needs to be reseted (http://meyerweb.com/eric/tools/css/reset/)
– Hunter style : the CSS “reset” from Nicolas Gallagher is an alternative fixing inconsistancies but preserving default styles (http://necolas.github.com/normalize.css/)
I personally use the reset from Eric Meyer.
