Want to add tag list to theme “journalist”

I’m using the “journalist” theme (scroll down here – http://lucianmarin.com/page/themes/) which I really like, but I’d like to add a tag list (not cloud).

I found this – http://www.themelab.com/2008/04/24/how-to-add-wordpress-tag-support-to-your-theme/ – but couldn’t get it to work. Also when trying to add the tag cloud under the widgets to the sidebar, it made it so only the tag cloud appeared (and wouldn’t allow anything else to be moved to the sidebar) and the modification from cloud to list didn’t work although as I do want the other items defaulted in the journalist theme – archive, categories, search – to remain so this wouldn’t be a complete solution anyway.

I’m pretty much an eejit and need every step spelled out – hope someone might be bored and feel like helping :-).

thanks
