You're on the right track on your list.
My suggestions:
I carry 2 leashes. A flexi that I clip on my hip belt for the trail and a long lead for camp.
You can use the bowl for both food and water. We try to avoid camping near water so you need water for her in camp if you do the same.
Booties depend on the dog. We live in the same type of terrain that we backpack in so my dogs have tough pads already and we've never had an issue. But a dog that has a grass yard and walks on sidewalks is a completely different story and there's all kinds of variations in between. But always check their pads at night. I carry super glue in my first aid kit for both of us.
Get a pack but don't put any real weight in until the dog is at least a year old. Check with your vet on that as different breeds joints are fully formed at different ages. Then add weight slowly as you go. But if you want to carry the weight, you're dog could go with you as soon as she's in condition.
I have a Zrest that I cut down. They don't have to be big if your dog curls up to sleep. My smaller one does but the bigger dog stretches out. I'm going to stop taking one in the summer as he won't stay on it anyway. But he's a warm sleeper. He's been out down to 8 degrees and I can't keep a jacket on him. Err on the conservative side with insulation until you know your dog.
Poop bags. They are light so always have some around. My dogs always wear their packs on day hikes as well so I just keep some in there. Bury it when in the backcountry but if I'm on my way out, I double bag it and put in in their pack. Then I have them lead or follow depending on the wind. :)
Some training stuff:
We always step off the trail for everyone and I put them in a sit stay. If people ask if they can visit with them, that's great. But some people are scared of ANY dog. My dogs are about as goofy and friendly as dogs can get and some people still walk past them as if they are Cujo. I have never had a negative comment about my dogs and that has nothing to do with their behavior and everything to do with making people comfortable as they pass. And always go to the downhill side for horses or other pack animals passing, of course.
A really handy thing to teach your dog (besides walking at your side on a loose lead) is to lead and follow. In steep terrain downhill terrain especially, I like my dogs to follow.
I guess that was a bit long winded. Your will teach each other more than anyone can teach you. I hope you and your new friend have many, many miles and smiles ahead of you!
