Regarding the second question, you might use the code we used at c:wolfenstein:Mediawiki:Wikia.css. Here's our implementation:

checks to see if a value contains the string. checks to see if a value starts with the string. I can't verify that it's any faster, but it seems like it might be.

Also note that my less-technically-inclined mind thinks that any slowness due to CSS selectors is different from any slowness due to actually connecting to a website and loading a page.

Psst, we also did it for monobook: c:wolfenstein:Mediawiki:Monobook.css
