I would park at the skills park if you want to do the whole thing. You can hit the whole park in a day but it's a big day. I have to say I seem to remember the park being bigger than this map, but I'm old and my memory fails me.
That lower left loop: not sure either direction is better. Just wing it.
On the right side, just hit Ray's Revenge from right-to-left on that map. That's from top to bottom. Also hit Hydra in the CCW direction. Sidewinder top to bottom is necessary as well.
If you split the park in 2, that right side would be best in this sort of order:
Buck
Allie
Grippis
Ridge
Ray's Revenge
Sidewinder-to-Osprey
Hydra CCW
Eagle
Sleek Dog
Fawn
Buck to the parking lot
Osprey might be worth going from the top, but it's been too long, I don't recall.
Stony connects the 2 parking lots. There are pretty much no rocks in the whole park with the exception of that trail. And suddenly it's like ALL THE ROCKS ARE HERE then gone.
Let us know how it goes. Been a few years so I am curious if the trails are being maintained there or not.
