travel agent/website for budget, independent travel for one month in western Europe?

I am planning a one month budget and independent travel in Europe but the planning tasks are simply daunting! Too many details to care about. I wonder if there are travel agents or websites that will help to book the rails, hostels and recommend a sample itinerey for the best of one month Europe?

I am reading Dummies and rick steves and simply too much to plan! any suggestion is appreciated.
Contiki looks good but I'd prefer an independent travel rather a tour (with people in a group). I am looking for a travel agent who can help to plan for a custom and not-group-setting Europe trip.

I would suggest Contiki or STA. The offer discount fares for students and people under 35.

for hotels i always use www.booking.com
