Answer 1

Maybe you can do the oposite: leave blank the URL Patterns to exclude and negate those patterns in the URL Patterns to Include box:

(?!..(bmp|css|js|gif|ico|jpe?g|png|swf|woff))(.)

Answer 2

As already mentioned in the question comments it is probably a problem with the trailing characters. The pattern matcher is executed against the complete url including parameters. So an URL http://example.com/layout.css?id=123 is not matched against the pattern .*\.css
The JMeter HTTP Request Sample seperates the Path and the Parameters so it might be not obvious when you look at the URL.

Solution:
Change the pattern to support trailing characters .*\.css.*

Explained
.* Any character
\. Matching the . (dot) character
css The character sequence css
.* Any character
