does this item have to be hardwired into my router or does it have wifi?

Does not have to be hard wired to your router. It has wifi.

Can I plug devices that are less than 8K into the 8k inputs on the back of the receiver?

Yes. I have plugged in a PS4 into that port for Game even thought it is not an 8k or capable of 120 4K. When going through setup and having the receiver recognize each device plugged in (create custom names if you want), the receiver sees it as PS4. With the receiver setup the PS4 works fine in the Game 8K port with no issues.

Can receiver do 2 zones for movie in 1 room and streaming in another at same time?

"Multi-Zone" (Zone 2 and/or Zone 3) is a feature in your Denon receiver that can produce independent audio/video signals to different parts of your home for a whole house audio (or video) application. With a receiver that supports Multi-Zone, (Zone 2 and/or Zone 3) you can play surround sound through your home theater application in one room while you have another room outputting an analog input signal, such as CD or Tuner. In addition, using the remote will allow you complete control of both zones independently regarding power, source, and volume. You can access a Multi Zone application in different ways with our receivers. Most receivers we manufacture are 7 channel amplifiers meaning you can power up to 7 speakers with the receiver. If you're running a 5.1 application, (5 speakers + a subwoofer) you would have 2 channels left over for use with a multi zone application. Your multi zone speakers would connect to the "Surround Back / Amp Assign" speaker teminals on the receiver's rear panel. You would then have to set the "Amp Assign" menu option to "Zone 2" or "Zone 3" depending on which zone you want powered
