My blog google search results url wrong

[-Xclusive-]

When i search my blog new posts google adds additional text to the url:

site/2012/07/post title/?utm_source=rss&utm_medium=rss&utm_campaign=post title

This has to be recent issue, because posts what were indexed earlier, has proper clean link.

Recently, 2-3 days ago, i added two additional sitemaps to google webmaster tools. Updated my BWP google XML sitemap also to a newer version. That last action deleted the original sitemap from my root directory and replaced it with sitemap.backup.xml.gz, sitemap.backup.xml (dif. name than the original one had).
I think i should delete one or more sitemap(s) from google webmaster tools. Which ones should i delete ? Both are already indexed and how should i avoid 404 links than? i have about 800 urls to delete than, is there easier way to do it?

Or should i just edit the google webmaster tools - url parameters section and chose option for everything "No: Doesnt effect page content (ex: tracks usage)" ?

Thanks
