Liam there is no really satisfactory solution to this on XF at the moment.
XF Pages don't have pagination, comments (your request) or bbcode editing (many other requests). I dunno why one of the coders hasn't stepped up on this one as the line of requests on these issues goes back to XF starting.
8WAyRun has done add-ons like a
portal but this doesn't create pages, it runs off forums which it display teasers on a portal page. I think this is different to what you want.
8WAyRun has also done a
wiki which does carry comments, and easy editing with bbcode; you can set yourself or mods to being editors. But you can't place selected pages in the main node tree and it's a bit odd on categories and navigation. You also have to stick to very short page titles or else the sidebar block screws up.
This coder is also very stretched and busy on running a lot of add-ons and his own large and busy site, so getting answers to wuestions either takes a while or doesn't happen.
At the moment I'm trying out
Contentteller an independent cms which is absolutely amazing in its features. Integrates witrh XF membership, usergroups. Single static pages - multiple paginated Articles - News items - Links directory - Glossary of linked keywords. Disable components you don't want. Build sidebars left/ right as you wish; and create a portal/ splash based on a lead component in the centre.
The developer is patient, courteous and responds to queries fast.
The main downside is no XF theme though it does have a good flexible design section at admin level. It should be possible to create a matching look. STOP PRESS: XF theme on the way see

The other downside is cost - beyond a lot of people's budget though uinderstandable for such a massive and well constructed software.
