David, I thought of these two additional resources in the event you don't know about them:
Refugee Trauma http://www.chcrtr.org/toolkit/
Immigrant Family info http://www.justice.gov/ag/defendingchildhood/tips-immigrant-familie...
Some of the info you probably already know but maybe a few new tips.
FYI, both these sites are mentioned on the TIC Toolkits page http://tiny.cc/tic-toolkits
