Do note that it's only the Greater crystal that allow you to crit against their respective targets. Least is just +1d6 (which is admittedly better than +1d6 from an enchantment, but still thoroughly meh). Greater also includes the effect from Lesser that lets you overcome their DR, and the Greater crystal is only 5k more than the Least.
Also, I want someone to doublecheck my equipment, an give some tips on what I should get.
Did you forget to add your Fast Movement to your speed?
Boots of Speed are questionable; there are other good boots for you, and there's a 6k Speed enchantment that gives 3/day 1-round haste with a swift action.
One obvious thing is the Cloak of Resistance +5. A Vest costs the same, but occupies a slot which has fewer good alternatives; a Cloak of Minor Displacement grants a continuous 20% miss chance, a Cloak of the Phoenix grants continuous flight at your land speed with perfect maneuverability, &c.
Instead of lugging rations, pick up a Survival Pouch or a combination of the lesser food+water+shelter items.
Instead of the lantern, get a Dull Grey Ioun Stone that you've paid a caster to hit with Continual Flame. If my memory holds, it should be 110gp for torch-equivalent light forever which you can stick in a pouch when you don't need it (plus 25gp for the stone itself).
As a fun aside, you could probably buy a bunch of dull grey stones and paint or pay for them to be permanently illusioned as decoys for the valuable ones.
At this level of play, you don't want a length of rope. You want a Troll Gut Rope, or if you're awesome, a Rod of Ropes. Or, again, flight/teleportation.
I... don't get the Blueshine. I mean, sure, it's cheap as hell and isn't a +#, but it's not going to make a difference to anything you'll need to hide from. Holy shit, I forgot about Nimble! Welp, time to change
my sheet around a bit, haha.
Sundering is eww. You're paying money for something that will help destroy loot.
Mettaline is cool, though, and the other two on your weapon mesh. Not much beyond that.
