To number one, it depends. You may decide not to interrupt what you are doing so it goes in the inbox or you might decide that it's easier to just do the action then. The choice depends on your context and energy and priorities of what you are doing. All of those make more sense if you are doing the weekly review regularly every week.

One rule is every night I toss in any unprocessed notes from my little carry around notebook into my inbox and every morning as I am drinking my coffee and checking the weather I process my paper inbox or at least all the notes from the night before. Reason is I've discovered I often think of things at dinner when hubby & I are talking that may have to be done next day or started the next day. I process those notes before they have time to get stale and while I can perhaps recall the conversation as my handwriting gets worse the faster I try to write.
