Like most people have said, your build will be more effective if you concentrate your free stat points on one or two stats based on the kind of cleric you want to be.
I am personally 25SPR rest END and I adore it.
My crit rate makes it so if I do solo, I kill slightly faster, but I still have decent HP/def.
I also agree that you should empower the power and cooldown of your main skills before SP. Essentials for any cleric imo, even if you plan on being a str cleric, are:
Power/CD on Heal
Power/CD on Rejuvenate
Other skills you might look into empowering based on the type of cleric you want to be:
power/CD on Bash
SP on heal
SP on rejuv
CD on revive (I don't do this, some people do.)
Duration on Invinc (I also don't do this because the damage cap is usually reached first, but some people do.
)
You could also save your skill points to empower CD of quicken at lv67, which is handy when paired with invinc.
