First of all, @Jackson4, you are not a burden. Happy to help you out!
Here's a screen shot of your weekly discount. The discount applies to all days of 7 or more regardless of what day of the week is selected.
And your monthly discount. Yes, the discount is applied for all days greater than 30.
As far as Instant Book goes, some hosts love it and others hate it. I have location issues as I'm pretty remote out in the countryside so I don't have it turned on since I want to discuss my location with guests to be sure my place suits their needs. My listing shows in nearby, larger, towns so many guests don't realize that the actual location is not in those towns. If that weren't the case I might consider Instant Book since I've gotten really terrific guests and haven't had to decline any reservation requests. One thing that really helps is to have Verified ID as a reservation requirement (to the left of Calendar and More). That cuts out a lot of questionable people. With Instant Book, though, it's really important to stay on top of your calendar to be sure any dates you don't want reservations are blocked. Also, you have to be sure the pricing is correct for as far out in the future as your calendar allows. Many hosts with Instant Book don't do this and are surprised by IB bookings, for say, New Year's, and they haven't adjusted their prices for the holidays. Personally, I don't allow reservations more than 3 months out so managing my calendar is a lot easier.
Yes, the "fake" booking is something you can do easily. Just go to a preview of your listing and put in some reservation dates and see what shows up. Don't press the Request to Book button, though! (The system probably wouldn't let you do it anyway since it's in Preview mode but I have never gone that far.)
Since you are a relatively new host, you might want to book mark this page which has incredibly helpful instructions for common hosting situations.
