We completely renovated an Edwardian house a few years ago, being as faithful as possible - what an exciting project OP!
Some books I can recommend for inspiration:
William Morris and the Arts & Crafts Home
Edwardian House Style
The Edwardian Gardener's Guide
If you're thinking of using wallpapers anywhere, William Morris would be the way to go, and I also found some vintage early 90s Laura Ashley paper on eBay - about 7 rolls unused - to do a small third bedroom. The decorator said the quality was excellent, much better than modern papers.
I wouldn't worry about toddlers and the stone flooring - I live in Portugal now where all the houses are tiled throughout. Kids aren't cracking their heads open.
That said, if you want an authentic, soft flooring for the kitchen, consider genuine linoleum rather than vinyl. Lino is warm, practical, eco-friendly and has a lovely linseed oil smell when it first goes down. It's produced under the brand name Marmoleum these days.
