Tired of being a scrub cleric

[Ptull]

Lvl 45 CLR and I'm embarrassed of my crap gear. It's a mix of handme downs, banded and lots of empty slots.

I have 5k to spend, but not sure how to spend it. Part of me thinks I need plate with CHA for lulls, but given that I'm mostly sitting in groups it feels wasted. So plate + wis seems the obvious choice. But should I prioritize plate or the wis? Given I'm rarely FM the extra mana would only serve to give me a nice started boost but be useless after the first couple of spells.

In short, I'd like to pointed in a direction and then I'll chase the gear from there.

Thanks for your input and time.
