Good start. If you own the stuff listed, take some of my critique with a grain of salt-- it gets down to small details and personal preferences. Nothing you listed stands out as a mistake or show stopper.
Have you tried the Triad and the 900ml pot? I'm not a fan of the Triad and wonder if it could boil 900ml in one go. It will need a wind screen. You can make one of aluminum foil, the heavier foil rigs as used with the MSR stoves, or some aluminum flashing from the hardware stove. Properly done, the flashing will fit in the pot with the stove. If you are going to go alcohol and haven't bought a Triad, consider a Caldera system. If you already own the Triad, a smaller pot may work better. If it works good for you, go for it :)
You will need more clothing. Doing the whole PCT will demand a varied clothing set that you can change as you make progress on the trail. By all means, check out Andrew Skurka's PCT gear list and seek others' experiences. You may need more puffy/layers than the Mont Bell. Perhaps a puffy vest would round out your existing collection.
As far as pants go, I see two options: running shorts with wind pants or zip off pants. I use light zip offs in the summer and have just switched to soft shell pants for colder/wetter weather. It doesn't make a huge difference on which zip-offs-- REI, Columbia, Ex Officio, Mountain Hardwear and Outdoor Research all make very usable ones. The OR Equinox convertibles have the least bric-a-brac on them--- no thigh pockets or other extras. I've given up on UL wind pants due to fragility-- you don't sit or kneel on your windshirt. Personal taste.
I like the Marmot DriClime windshirts, BUT they aren't versatile enough for a through hike. An UL windshirt coupled with other base layers will give you more options for the weight. A light colored wind shirt is handy for bug protection without cooking yourself.
I like Power Stretch for mid layers. Consider SealSkinz gloves for long days in cold rain.
Ditch the pack cover and use a garbage compactor bag.
Don't forget your hygiene items. They can add up, even when using smaller bottles-- stuff like soap, insect repellent, dental care, hand cleaner, TP and trowel, etc.
Totally my opinion, and others may do back-flips, but I haul more knife than the Classic. For SUL food prep, the Victorinox 3.5" paring knife is 0.75oz and $4.50. I like a 3"-3.5" folding knife. The Swiss Army Hiker, Farmer, and Trekker are personal favorites. My "best" knife is a Benchmade Griptilian. Another option is a Mora Allround for a fixed blade knife, providing good backcountry survival/repair/food prep service. 4.1oz and $15.
Packs. I'm getting old and cranky on packs. I own a Jam and I think it is a lot of bang for the buck. You can buy lighter packs, but they won't be as durable. If you want the lightest possible kit, frameless packs are the way to go.
My complaint du jour on frameless packs is twofold: comfort and packing. You can improve the weight transfer on a frameless pack with good design and careful loading, but IMHO, it will never equal what a framed pack can do. Loading a frameless is a pain. I'm switching off to an Osprey Exos and taking the weigh hit-- better weight transfer, much better back ventilation. Too many gee-gaws for my taste, but I'm going to try them all out before doing surgery.
