I cannot comment on the OOS chances, but I would personally put UCSD and UC Irvine as reaches. These schools have an overall admit rate around 25% and they will not see your SAT score or teacher recommendations.
I am not completely sure from your description what major you are planning to apply to at these schools, but computer science would be a tougher admit. If applying for computer science, UC Davis would also be a reach.
Here is a link to historical UC admit rate and GPA range by discipline that might be helpful. The GPAs shown here are UC weighted capped.
This is another good resource especially for CA HS that send a lot of kids to UCs. You can look up your own HS for historical admit rate and GPA ranges (weighted capped).
CPSLO admit rate and admit likelihood will depend entirely on what major you apply for. Computer science would definitely be a reach.
