The first item you will be creating as an Enchanter is a Runed Copper Rod, which you will need in order to do enchants. You will need to upgrade this rod at regular intervals as the recipes become tougher and require better rods.
The Copper Rod is bought from most trade good vendors, or enchanting suppliers.
You get Strange Dusts from disenchanting level 5 to 20 uncommon or superior items.
Just buy a some crappy bracers and repeat the enchant on them. Alternately, you can get a tailor, leatherworker or blacksmith friend to create some low level bracers for you.
Use the same approach for subsequent recipes.
Alternate route to (I think) 50 is to just disenchant lots of low level items. I'm not sure if this route is viable anymore though (been quite a while since I levelled enchanting, so I've posted the other way as well).
