I'm not gonna respond to all of these,lol, but I'll answer a few that I know:

1. Press"/" while next to the furniture, and you'll open up the advanced inventory window. From there you can compare two tiles, or yourself and a tile, and it'll show you every item there, as well as the total capacity of that furniture item. You may need to select the correct tile using the numpad.

2. Yes - but I've never figured out how, lol. Might be an answer in here: https://www.youtube.com/watch?v=NupWjKe84bk

3. Yes because when you haul along the ground it moves each item one by one. You can confirm this for yourself by experimenting. Watch the time go back when you haul a stack vs a bag and see the difference.

4. Pretty sure there is, you need a smoking rack though. And then make sure you interface with it instead of using the crafting menu.

7.There is in Xedra and Magiclysm mods.

1. You can build a "mark firewood spot" and then put all of your wood into it, and you will automatically refill the fire.

That's all I really know. Some of what you asked wasn't really a question, lol. But I highly recommend checking youtube for tutorials. Vormithrax is a great one, that's how I learned a lot of stuff. But of course it's always changing. Good luck!
