For processing 4x5 sheets without a darkroom you have a few options:
The Taco Method in a daylight tank -
Mod54 - http://www.mod54.com
HP Combi Plan - http://www.bhphotovideo.com/c/produc...Combi_4_x.html
And the elusive Paterson Orbital processor.
Each has their own advantage, if you've already have a Paterson tank I'd try the taco method first, I've had good, even results with it.
Literature, I'd recommend Stroebel's 'View Camera Technique'.
EDIT: Of course, http://www.largeformatphotography.info too.
Best of luck.
