Incorporating previous/next links and RSS into theme

Hi All,

I’m blogging at: http://www.soundofruins.net using the Ultralight theme.

Unfortunately, the stripped-back theme does not include pagination functionality – creating pages for posts in sets of ten and including a previous/next link down the bottom of each page.

It’s also missing any RSS feed that I can tell off – even though the theme comes with a default RSS link in the top right, when you try to add the url to a reader it says no feed exists.

Now I’m quite new to coding, so I would appreciate any help – but just bare in mind I’m a bit of a newbie – I’ve copied in the index.php code below as I suspect that’s where I might be able to get pages somehow? The theme designer suggested this in the comments to the post linked about, but his solution did not work at all for me.

Thanks so much for any assistance in advance, really hoping I can get this sorted out as I’ve spent so much time customising bits of the theme already it would suck to have to start anew with another one.

Cheers!
