Welcome aboard the RoadTrip America Forums!
I am only somewhat surprised that you couldn't find a thread that specifically answered your questions. Each RoadTrip is unique - that's the point - and given your general itinerary, you'd be looking for a needle in a haystack. Nevertheless, take a look at the discussions linked to from this post and this post and you should find something close or at lest some useable ideas. Just in general: your trip is manageable in the time you have available; you should certainly take the Pacific Coast Highway (CA-1) south from San Francisco to Los Angeles; and (depending on how much time you spend in L.A. and Las Vegas and whether Tioga Pass is still open) return to S.F. by way of Death Valley and Yosemite.
Baseball, I'm afraid will be out of the question. The regular season finished up yesterday and the playoffs begin tomorrow. There is only team involved from your route, the Angels, and tickets will be impossible to get even if they are still playing by the time you get here. Minor League ball ended a while ago and college teams typically don't start playing until Spring.
