Just saw Dulfy put up a bunch of 5.0 guides which including gearing stats.
Also, if we want to start getting some higher up Mods we should start farming NiM first bosses for the schematics for those 340 mods and whatnot. Not to mention if you can craft em you can make a killing on the GTN.
There's still debate over how well each stat works now. Like people saying to have 110% accuracy or to only have 40% crit instead of going higher. I'd like to either run some parses myself or talk to someone that has tried the various methods of gearing in accuracy and crit
