Greek Web Masters

I have read the FAQs and checked for similar issues: YES / NO
My site’s URL (web address) is: www.mindmotivations.com

Many of our pages are not indexing properly – namely the product pages. Tried everything I know of and what Google told me to do – 3 months now:
Canonical meta tag
Unique Page titles and descriptions
Unique Content Descriptions
Blocking the native Drupal URLs – i.e. /node/2812 – we use sef urls – i.e, /shop/product123
Rewriting product descriptions
Reconsideration from Google webmaster
Redirecting 301 old urls (we redesigned our site 5 months ago) products used to rank well
Moving URL closer to root – (took out /products/…. from all product URLs

Was wondering if anyone would care to take a look at see if you know why?

10 or so products out of 150+ are indexed
For example: http://www.mindmotivations.com/shop/weight-loss-amp-appetite-control is indexed
but http://www.mindmotivations.com/shop/quit-smoking does not index

Help is appreciated here.
