Don't know about playing a monk always use a custom class
As for enchant it has three effects
1: Allows you to make your own enchanted (magic) items. You need a spell with the effect you want to use and a filled soul gem of some description. Just put the soul gem in your hand and it will give you the option to enchant or recharge items,m and well off you go
2: This is a more subtle effect. This allows you to use enchanted items more efficently. It means you get the same effect for less charges (Fargoths ring as an example).
3: You get more charge from a soul gem when using them to recharge items (not actually more charge, but more of the charge goes in)
Hope this is helpful and apologies for metioning the annoying one
