There's a Rune Encyclopedia here in the forums.
Welcome to the study of occultism. :D
To begin spellcasting be sure to well acquait yourself with basic knowledge on subjects that serve as a foundation to casting spells. Things like meditation, visualization, energy manipulation, your chakras, moon phases, herbs, casting circles, etc...
I do not suggest casting spells for whatever reasons as long as they seems simple enough. For beginners I suggest just sticking to studying spells and developing your own personal knowledge of how they work.
A lot of spiritual work can deal with gods you're more attuned to so to kick off on the magick side of worshiping the Norse gods try becoming more familiar with they're aspects, personalities, stories, symbolism, and general history (look into planetary comparisons too).
Good luck Cvisscher :)
