Did some quick testing on mana regen, timing how long it took for mana to regenerate after a bout of spell casting with different gear and at different levels.
Here's a table of the results, all tests conducted with Sedna:

The short summary: Max MP has no effect on mana regen. +MP/second gear does exactly as advertised. +% regen gear also does as advertised, adding a percentage of your MP/s on top. There's also a base regen rate based on your level. I'm sure it's also affected by class, but I haven't tested that yet.
So the formula is something like (baseregen+regenmod*level+gearregen)*(1+%regen/100)
Baseregen is the characters regen at 'level 0', for Sedna that would aparently be 3.5. Regenmod is the amount gained per level, for Sedna that would be .3 MP/s per level. Gearregen is the +mp/s from gear. %regen is the +% regen from gear.
Did I miss anything?
