If you need hand-holding, I suggest you go the traditional route and find a travel agent.
When I planned my Europe honeymoon, we did most of the homework on our own and still went with an agent to book some of our stuff. Albeit she was a family friend, it's just nice to have an extra resource.
Here are some sites we used from what I can remember:
Wikitravel - The Free Travel Guide (Gives you a summary of the destination and some local tips)
Google Earth or Google Maps (Helped a ton to find our way around and gives you a first person view when you do research)
Travel Europe with the Eurail train pass | Eurail.com (We trained from Rome to Paris, which honestly was a mistake looking back due to the length of the ride. But I'd highly recommend it for short distance trips to close by cities and if you plan on taking it more than once as the price gets better)
