Skills are completely independent of \"class.\" There are many of them available (though not all implemented yet), and you choose the skills you want to work with. You can be a warrior, and choose between swords, daggers, axes, melee, etc., or be a mage and choose between the six different ways, or \"schools\" of magic, you can be a crafter (or weapons or armor), cook, builder, musician, etc. Though as I stated, the current choices are limited (and searching through the forums will let you know which skills are currently available for increasing). Armor does not go by race, nor does equipment, though many weapons require either a certain amount of strength or agility, I believe, to equip and use.
