where do i submit my url ????

1. Go to http://dmoz.org/
2. Find the top-level category that best encompasses the content of your website and click on the link.
3. Find the next-level category that best encompasses the content of your website and click the link.
4. Repeat step 3 until you are at the lowest possible level that is still relevant to your website.
5. Click the "Suggest Listing" link in the top right corner.
6. Follow the instructions on the form and submit.

Does google can submit site, too?

Click on the "Submit a Site" link on the bottom of http://www.google.com/dirhp and note where it takes you. (To http://dmoz.org/add.html )

So yes, you can submit to dmoz using Google.
No, you don't need to submit to both Google and dmoz separately. In fact you can't.

I hope that answers your question.
