USC is a private university, so everyone pays the same amount. Your competition would be rough, but you can explain the dip in your grades with the essay for USC.
The OOS publics will charge you the OOS rates.
The UC’s have a minimum GPA requirement. The minimum GPA for California applicants is 3.0. It’s 3.4 for nonresidents, so the very competitive UCLA would be out. http://www.admission.ucla.edu/prospect/adm_fr/fracadrq.htm
SDSU uses the Eligibity index.

@Gumbymom can give you more information on the stats required for entry.
You can research the minimum GPA requirements on your own. Google is your friend:)
