This might be common knowledge, I'm not sure. I recently learned these things and I just want to spread the word about this to people who don't know.

1. You can adjust the zoom in 3rd person my clicking the right stick and using the left stick to zoom in/out. However the zoom for having your weapons ready is always fixed I think.

2. You can use a single hotkey for 2 different weapons. I cycle between a Greatsword and Dagger on my right hotkey. To do this, hotkey a weapon. Equip is using the hotkey. Then go into the item menu and equip another weapon. You can now use the hotkey to cycle between both weapons.

For example my hotkeys are (Left, Bow) (Right, Greatsword) However I can cycle between the Bow, Greatsword and Dagger using the hotkeys only. This is helpful to me because I use the dagger for sneak attacks and the greatsword for full on combat. I'm not sure if this works with spells.

Bump for knowledge

1. Did not know. I didn't play 1st person so it's understandable, but it's good to know.
2. Not really sure i know how to do this either. I use weapons, and favorites menu, havent hotkeyed anything. (Use Xbox)

With regard to 2., you're toggling. It'd quite useful for moving between bow and melee weapon. And yes, I figured that out just a day or so ago myself.
