If I were to drive the coast road I would head south down it which will put the Ocean and it's scenic pull outs on your side of the road. However I see that Disney and Big tree's are a must and with limited time I would agree along the lines of what Buck suggested. After Sequoia you could head towards Morro Bay and do part of the coast back to LA and perhaps check out the 'Danish village' of Solvang on route.
