I think that you are a little heavy for the items you've listed. Try to get the big 3; Backpack, sleep system and shelter below 2-3# each. I wouldn't carry the Nook, the Leatherman, the knife, GPS, or the Emergency Bivy and the thick socks. Find things that are lighter and more multifunctional like the Swiss Army classic knife instead of 2 tools. Look for shelters along the lines of the Six Moons Designs Gatewood Cape or the Wild Oasis. Start reading the PCT-L archives and the Trail Journals of other long term PCT hikers like "Piper", "Steeleye" and "Schroomer" to name a few. Carry the lightest water bottles with enough total capacity of 6-8 liters. try to go stove less as this year is the longest drought in recorded history. For a ground cloth use the Gossamer Gear Polycro. The Sawyer mini filter is faster and less fiddily than aqua Mira. Download Halfmiles maps and purchase Yogi's trail guide or Eric the blacks guides. Here's a good gear list for SoCal; http://trailability.com/gearlists/three-season-jhauraw/
Above all just carry enough to get you from town stop to stop, and be prepared to shed non essential stuff and know you can probably pick up anything within a day or two along most of the trail. It's not about surviving but the knowledge you have will be the lightest and most valuable. When you get to San Diego I can help you get to the PCT Trailhead. I host hikers , give rides and cache water at the 3rd gate in the dessert.
