You have a VERY good chance at getting into all those schools. You will have about a 3.85 weighted, which is about average for those schools, and you have EXCELLENT SAT Subject scores. Don’t worry about how many a-g classes you take, as long as you go a little over the minimum it doesn’t really matter, You also have very good activities to make up for your poor SAT score. I would recommend picking up some more clubs, and taking up a leadership position in some of them, like Vice-President or something. If you get around a 1900, you should be a shoe-in to get into any of those colleges. Still, even with a 1680 you have a very good chance to get in.

UCSD and UCI are very competitive, but UCSD and UCR were not impacted, last time I checked.
