Hi,
Your plan sounds good. :) Although you can buy train tickets separately from one place to another (and turns out to be cheaper), I think it'll be easier for you to get a Eurail pass since you are travelling alone. More convenient for you. If you are under 26, you can buy a Benelux-France Youth Pass (covers Belgium,the Netherlands, Luxemburg and France). Prices are::
4 days in 2 months $204.00
5 days in 2 months $231.00
6 days in 2 months $257.00
8 days in 2 months $308.00
10 days in 2 months $359.00
[can choose to buy a pass with unlimited travel in 4,5,6,8 or 10 days] I guess you can choose between 4,5 or 6 days la, since you won't travel much between those countries (thus you won't need the train that much).

or you can choose to take the coach? [

Regarding the accomodation, Le Village is okay. But it seems they only offer mixed room (with males and females in one room).... Absolute Paris is quite nice. You'll get free internet, free breakfast, free map etc... and they have private (single) en-suite room too.
You can find all the hostel info (for all other countries) on
