help with rss

You don’t need to install anything. It’s there:
http://www.hawaiionyourown.com/blog/?feed=rss2

What do you mean?
You don’t show the feeds – they are just there for feed readers. If you meant to display a link for them: just use a normal anchor tag with whatever text (e.g. RSS feeds) and the above URL.
Or look how it is done in the footer of the default theme.
