Could someone explain to me what you have to do?

I am new to this. Say I have 100 links that I have created on blogs, social bookmarking sites and other areas of the internet and I know want to make sure they get indexed.

I keep reading that creating RSS and telling the search engines to crawl that will increase the chances that they all get credited as pointing to my site.

Are there tools, ideally free, that will allow me to do this? If you could as close to a step by step would be brilliant.

Thanks in advance
