WordPress sitemap

Hi:

I own my domain and host a WP blog through it. (HERE)
Now my question is, how can I sumbit my sitemap so the search engines can crawl it? I know if you host with wordpress it does this automatically for you. What about my situation?

Should I use Google analytics and webmaster tools?
I just migrated all my blogger data to wordpress and I was using the google webmaster tools and analytics previously.

Thanks a lot.
