Info about Santa Fe Springs, CA in Los Angeles?

I'm hoping there are some folks here on BPN who grew up in the LA area and can give me some advice to pass on to my sister.  Her husband is considering a job in Santa Fe Springs (near Downey and Whittier in LA- about 30 min from Long Beach), and they have NO idea about the area.  My online searching feels like I can't find the personal kind of information I want.  It looks like they would be in Little Lake City School District? Can anyone point me the right direction or recommend good neighborhoods and schools near that area? They have 4 children- from high school age through pre-school.  Thank you so much for any advice you can give!   You can email me at laura b fig at gmail (remove spaces).
