Most people don't include worn clothing in their baseweight, so you're almost there already. I notice you list a map for the Appalachian Trail going through Shenandoah National Park, so I'll assume that's where you're going. I'll also assume you're going on a trip this summer. If not, you might want to ignore some of this advice. I'll try not to repeat other people's advice.

If you plan to follow the AT then one thing you can ditch is the map itself - a single sheet elevation profile should suffice. That won't save you much weight, but every bit counts.

Pack covers get a bad rap. I like 'em, but you might benefit by replacing it with a 2 oz garbage bag. If weather's good, you'll save a couple oz. If weather's bad, you'll probably gain back the weight from water in your pack ¯_(ツ)_/¯

Consider ditching the pillow; if you need one to sleep, you can use some of your other gear.

DON'T just change the pack. It's one of the best packs around for a heavy load, and if you can't change your base weight much that pack's pretty great. But, if you do succeed in dropping your base weight by changing other gear, switching to a smaller pack would be a good additional change.

That tent isn't ridiculously heavy, but you could certainly get something lighter. There are quite a few shelters along the Shenandoah AT, so you might not even use it half the time. Maybe look at tarps?

If you plan to make hot drinks, the mug is good. If you don't (I never take the time) ditch it.

If you're going on a short trip (a week), you probably don't need the Sawyer Syringe with you. But clean it when you get home. You also don't need a stuff sack for a sawyer - just wrap the bag around it, leave it in a pocket.

The AT is rather humid, so when it rains you get wet. Rain gear won't keep you dry, but it can act as a heat shell to keep you warm. So you can ditch the rain pants. If you're going in the summer, you can make do with a much less substantial rain jacket too.

Contrary to the theme of this thread, I do recommend having an extra set of clothes to sleep in on the AT, simply because you want to sleep dry. This can be pretty minimal though, so ditch the spare shirt, but keep a spare baselayer. Not the one you have though - it's kinda heavy. A synthetic walmart shirt would be sufficient, and lighter. You also probably don't need a bottom baselayer for Shenandoah in summer.

You probably won't need gloves.

You don't need a backup firestarter. If you like campfires then the tinder is fine - if you see it as an emergency supply, ditch it.

You shouldn't need an emergency heat blanket, and in the event that you do the solution is to get walking.

Stay on the trail, and you won't need a whistle. Also, your pack has one built in.

You shouldn't need a backup water filter. I carry Iodine for the convenience, though, whenever I'll need to actually carry water (rather than taking the camel approach). In Shenandoah, it's worth it IMO.

I wouldn't bother with bear spray, but that's up to you.

Your first aid kit is heavy. This is a video of a 1 oz kit. That might be too minimalist for your comfort, but you can probably go lighter than 7.7 oz.

You do not need an emergency stuff sack.

99% of the time you use rope while camping, it's for a bear bag. Often in Shenandoah you won't need to (because bear poles), but it's vital if you're camping away from a shelter, in which case you'll actually need MORE rope - about 50 feet is good.

You don't need a compass on the AT.

You could have a smaller knife, but you're pretty close.
