I couldn’t open the property to look at item 2 – so first let me help you solve item 1, then we’ll move to item 1.
page not found.
To me it seems you modified in Admin – Permalinks the link structure from default to a custom form, BUT you don’t have HTACCESS in your WordPress install with the right permissions enabled. This is WordPress must if you want to change permalinks structure.
This is not theme related, but I can send you our HTACCESS if you need it. This is the WordPress documentation about this http://codex.wordpress.org/Using_Permalinks
If you need the htaccess from me, please send me an email at [email protected]
