Work / Potential work and new life for Native English speakers in Warsaw [6]

I will be moving to Warsaw in September (2010) with My Girlfriends job. I am a CELTA certified Native English teacher with over 2 years experience. I am presently teaching Business and conversational English with a school in Bratislava, Slovakia.

Can anyone offer advice about schools? For example, what schools have good/bad reputaions and why?
I am also interested in any information about life in general, Does and dont's, Expat communities and so on.
Thank you in advance for any help.
