Power is a great stat to stack since it isn't subject to diminishing returns unlike Surge/Crit/Alacity/Expertise. This is why you should always use Power Relics and Adrenals.
The value of Crit depends on the spec you play and hits harsh DR at about 35%. I wouldn't stack it higher than about 30%.
Surge is a pretty good stat but shouldn't be stacked over ~75%. DR are so intense that it's virtually impossible to get over 80% Surge.
The value of Accuracy depends again on the class and spec you are playing. The importance of Accuracy is commonly overrated since Force Attacks already have 100% hit chance. Only dual-wielding classes seem to gain more benefit from Accuracy than others.
So in summery Main stat = Power > Surge (up to 75%) > Crit (up to ~33%) > Alacity/Accuracy.
PS: All this is subject to change in 1.2 where there are going to be a number of changes to stat formulas.
