Does the trifolate orange bear fruit currently?
If not, might be a sign that overstory clearing would be beneficial. Thinning the pines could be easist. The acorns from the oak would help support ecosystem diversity squirrels, deer, etc
Have you researched the usefulness of the species you are removing? You might consider flagging a few well placed of each current variety to keep.
The species you mentioned replacing them with are more susceptible to various maladies. Ie, higher maintenance.
As for the task at hand, a bobcat with brush clearer on the front would likely be fastest way. If you can find native varieties of target species, that could help keep maintenance reasonable.
Other understory species to consider: pawpaw, persimmon, wild plum, blueberry, huckleberry.
