With the consolidation of ratings, I made a little list of the new values of certain enchants and gems. It seems that there is some fine-tuning to be done, although this is probably low priority for Blizzard.
Enchants
Bracer - Superior Healing (+16) is better than Spellpower (+15), and also cheaper
Gloves - Major Spellpower (+20) is better than Major Healing (+19), cost is the same
Gloves - Spell Strike now also adds 15 melee/ranged hit rating, new best rogue enchant?
Weapon - Major Healing (+43) is better than Major Spellpower (+40), but also more costly
Ring - Spellpower (+12) is better than Healing Power (+11) and also cheaper
Gems
Not so much change here, just a note that certain gems are now exactly the same due to rating consolidation, and we finally get physical haste gems.
Red Gems - Runed and Teardrop are the same (spellpower)
Yellow Gems - Great and Rigid are the same (hit rating)
Gleaming and Smooth are the same (crit rating)
Quick now also gives melee/ranged haste rating
Green Gems - Forceful now also gives melee/ranged haste rating
