Humm, you got some really nice questions there!
Just try to remember that OSX is not Windows and you'll be facing a learning curve in the first few weeks, some things are just different and I bet you'll get used to it in no time.
For instance:
You were asking about the cut feature so "taken for granted" in Microsoft's OS, although it seems kinda stupid that such basic shortcut is lacking in OSX we have to find a way around it.
I don't know if you know what "spring loaded folders" are but it can be quite handy. Let's say you want to move the folder "Work" that is placed in your desktop to your documents folder, instead of thinking about keyboard shortcuts like Cmd + X or opening two Finder windows, just try to drag the folder "Work" over "Mac HD" and stop for a second.... it will open a Finder window with that (don't release the mouse drag), then drag it into your Sidebar over "Documents" and let go of the mouse button, ok, Done! A Cut/Move done in seconds 🙂
If you wanted to nest that folder in a deeper folder just keep dragging on top of folders and they will open up for you, if you wish to cancel hit Esc or (while still dragging) move the mouse cursor off the Finder window.
Guess that was a long explanation but Spring loaded folders is one of the best OSX features IMO, and it's a good example on how you can let go of the Windows way of doing things and start adapting to OSX 🙂
Anyway, hope it helps, best of luck with your Mac!
