Nice theme. 
1) How to add menu items (pages) to top menu? I would wish to add Privacy, Terms, Pricing. I notice pages in admin only has an option to add to footer.
2) In the main categories I have added to extra categories, how to do I go about adding these 2 extra categories to the footer category links.

Thank you

1) When you edit page (static) in osclass oc-admin, mark page with "Show a page in footer". This will add page to header
2) By default, you can show up to 8 categories in footer. Those are automatically shown there. If you want to show more categories, go to footer.php located in theme folder and find this line:
          <?php while(osc_has_categories() and $c <= 8) { ?>
and change it to:
          <?php while(osc_has_categories() and $c <= 10) { ?>
To show 10 categories.

Thanks  frosticek  for your prompt reply/fix.
Was able to resolve these two minor issues.
