I do still use the meta-description tag, it's good for usability. Typically...well occasionally Google will use it to describe your page on the SERP. As far as the keywords tag though, I think after all the abuse it got in the 90's and early 2000's it's not valued to major search engines.

I know Danny Sullivan ran a long test on it, you can check out the results here:
