Start, However small.

Hello all
I have started submitting this new website for which I am trying to do some SEO myself.
I have found many links to great directories and search engines from this forum. Using the add url page, i have listed the site to many of them.
Till yesterday evening, google SERP for the domain name yielded no results. But today when i tried it again, i could find the link to one of the directories on which i had submitted my site. The directory is www.splut.com.
Now, my question is whether such listings help the spider to crawl my site instatenously?
Apart from trying to get back links from sites which are already listed in google, should i continue such submissions?
BTW, going through all these posts on this forums, i have started making this one ground rule for seo. Create good contents, they will come searching for you. But the wait can be long and boring.
What do you guys say?
Thanks
