You've literally just missed the peak hiring time for jobs in Europe. Of course, there are some jobs available, but nowhere near as many as there were a month ago. There will be a smaller hiring peak in very early January, more often than not to replace the teachers who jumped ship at Christmas. You'd probably have to hit the ground running so these may not be the best positions for a newbie.
As I said in my previous post, International House schools generally provide a fair amount of assistance. Accommodation is likely to be shared with other teachers, although these teachers will probably not be newbies as schools tend to hire a mix of rookies and experienced teachers.
I'm afraid that there isn't a jobsite specifically aimed at newbies. For jobs in Europe, your best bet is http://www.tefl.com/jobs/search.html
. You will have to read through the ads that interest you to find out what assistance is offered. Help with tax numbers and social security generally comes as standard. You may be given assistance with opening a bank account, although in two of the countries I've worked in I was simply pointed in the direction of the bank and told to sort it out myself! Likewise, accommodation may be found for you or, as is the case here in Madrid, you may have to find your own accommodation, which isn't as scary or difficult as it sounds.
