Highend Update – then some pages not displaying properly

My site http://www.tresorellesalon.com has a few buggy pages after recent 2.0 upgrade. I had to restore to back to 1.7 – but several pages are not displaying properly still. The url ends in ‘*’ instead of the post name as structured in the reading setting. Also the links at the top (phone, map & email) have been effected and do not work on affected pages – but do work on functioning pages.

Examples:
Displays correctly: http://www.tresorellesalon.com/our-products/

Not displaying:
http://www.tresorellesalon.com/our-products/ (team member do not display – but pages exists)
http://www.tresorellesalon.com/contact-us/ (text exists on page edit – does not display)
and http://www.tresorellesalon.com/ (home page missing featured content)

Help! THX!
