Hey guys, I just wanted to know if there's a way to change your sites details on google. I submitted to google a few weeks ago and was accepted etc no worries. But now I need to change my keywords and whatnot because I have to optimize for a different phrase. One with only 10 600 Competing sites I might add.

So it's pretty important I do! Thanks for any help

Well, all you need to do is to change the keywords on your website. Once google spiders it again they will have your changed website listed. You can also create a xml sitemap and submit it to google, this helps to speed up the whole process.
Therefore you need to create a google webmaster account (it is free).
