Hey kids! I'm a newbie here, so please be nice!

I'm gonna ride the Miramar MS Bike Tour(only the 100mi, not 150)in October...and I want to start to ride to work a few times a week to get some extra rides in....and was just looking for some advice on it. I have yet to find what looks like a good(well...safest...) route from Long Beach to Torrance(more like Gardena actually), so, any ideas for that would be super!
