I am a travel nut… so maybe I can give you some pointers on Trip Planning and resources you might find useful.
First and foremost check out Wikipedia… I find it is a great place to get a General Overview of a place you are considering but never been to before… start with the entry for California and go from there… (Napa-Sonoma-Santa Barbara)
Wikipedia – California= http://en.wikipedia.org/wiki/California
Also you’ll need a good map to figure out where things are and distances… I like GOOGLE MAPS for this… as you can also see things in Satellite & Street View… or ask it to find things like Hotels, Restaurants etc.

Next check out the various Official Tourism Websites… almost every Country – Region / State / Province … and City have them nowadays
California Tourism = http://www.visitcalifornia.com
Napa Tourism = http://www.nappavalley.com
Sonoma Tourism = http://www.sonomacounty.com
Santa Barbara Tourism = http://www.santabarbaraca.com
As well as some for the California Wine industry…
Discover California Wines = http://www.discovercaliforniawines.com
You will also find that when it comes to Regions… that there are usually a wide variety of websites with info on what to see and do… certainly true for the California Wine Regions… you can put in Napa, Sonoma, or California Wine and find a whole bunch of stuff in GOOGLE
Lastly, be sure and check in with TripAdvisor. The internets foremost Travel Planning Website. Lots of great stuff on there. Be it their Travel Guide Pages (link below)… OR their Reviews on Accommodations, Restaurants and Attractions. Or their fabulous Forums (like the Boards here on WBee) where you can chat with Destination Experts and Locals to ask specific Questions about visiting an area
(or just read thru active and past topics for ideas / info). Personally, I won’t plan any sort of Vacation / Getaway without consulting TA first !!

Hope this helps,
PS… Winery Touring can be a very romantic thing to do. Mr TTR and I haven’t been fortunate enough to get to California yet… but we’ve done our share of Vineyard & Winery Touring in Canada and the Northern USA… and LOVE it, and am sure you guys will to… just remember to pace yourselves if you are self-driving… otherwise look into organized touring where someone else does the driving, and you guys get to enjoy all the more. Touring Groups are usually a lot of fun in that you get to meet other people, get more of a “wine education” (at least on the good ones) and often they include things like meals, or special things that the person who just walks up to a Winery won’t get.
