Local variations and cults for different gods sprung up in different spots, but for the most part, Anglo-Saxon Heathenry is very much like the heathenry of mainland Europe, or Norse heathenry (of the Eddas). Many of the gods and their attributes carry straight over, then there are others that have completely different gods for things. (Say, Njordr was the Norse god of the sea, and Wade was the English god/giant of the sea.)
You can get a feel for how alike many of the personalities and tropes are by comparing something more contemporary, like Jacobs' collection of English Fairy Tales to the brothers Grimm collection of Fairy Tales.

~~From there you should be able to find info online on most of the gods/figures and how they work together.~~

If you want to truly dive into the details, get yourself a copy of The Elder Gods by Stephen Pollingon.
