For processing 4x5 sheets without a darkroom you have a few options:

The Taco Method in a daylight tank -

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.
