Why was my Canon Speedlite 600EX triggering other flashes?

The reason you were triggering the other flashes is that the other photographer is a rookie. She was probably using the flashes as optical slaves... bad decision. Even if she was using a radio ...

Why aren't my strobes and speedlight in sync, and how can I fix this?

If it were the 380EX that was having issues triggering the strobes: The most likely scenario would be that the pre-flash of the E-TTL only 380EX is triggering the strobes before the shutter opens. ...

Will a 600rt Flash work with a 70d using radio control?

Yes and no. So far (Sept 2014), no Canon bodies can trigger the Wireless 600EX-RT flash via RADIO. However, a 70D can trigger it via OPTICAL (ie flash pulses) method, same as a 580EX/430EX etc. So, ...

Can I trigger a Nikon SB-600 off-camera with any other flash on the hotshoe?

In Nikon speedlight terminology, the feature you want is SU-4 mode. The SB-600 does not have it, the SB-700, -800, -900, and 910 do. There are similar "dumb" slave modes in the SB-26 and SB-28DX. ...

What should I look for in a wireless flash trigger for a home studio?

Actually, the most problematic part of your equation here is the 380EX. It doesn't do Canon's wireless eTTL slave mode, which is probably why you're looking for triggers, but it has no manual power ...
