Re: destination URL
It can affect relevance and QS if the system decides that the keyword-level destination URL is a better (or worse) "fit" for the keyword and the related searches than the destination URL used at the Ad Group level.
You might want to test and see which gives you better results.

I think its all about how you want to manage your campaigns. Setting Destination URL's via ads or keywords will be treated the same, as far as I'm concerned, there is no QS benefits to either one...one is not better than the other.
This is assuming you have a specific URL that you would be setting at either the ad group or keyword level. If you're talking about very specific and different URLs, there could be differences.
