For all what is in game is best the 1.6.4 rus manual (it is easy to decipher when you are looking only on stats of artefacts or wives etc.)
for wives you can read and use the thread of this forum:

There are even some artefact threads in this forum as well, but mostly scattered based on sets or upgrades or quests... so I would advise to turn to the rus manual
