I love the Eclipse change. That's a not insignificant Balance dps buff. With the Empowered Touch change, I might rethink my Resto spec, too.
The Balance of Power change is... interesting. By removing the miss chance, Blizz is actually getting rid of one of the benefits of this talent in PvE - the increased chance that some random boss debuff or spell will fail completely. This has saved my life on more than one occasion. On the other hand, with all the hit rating being handed out on gear, the talent was useless in PvP, where it was probably intended to have the most benefit. Now, it'll act as a passive magic damage reduction in all cases, which is a big PvP buff and very very slightly useful in PvE, unless you're Panzerkinning.
Owlkin Frenzy is still a PvP talent, unfortunately - even with the mana regen I can't see that it's all that useful in PvE, although I'm sure the theorycrafting folks will be all over it.
