>Powering via the GPIO header is fine. All the 5V pins are directly connected to each other. But don't rely on the colour coded header as you've installed it the wrong way around.
yea i had that in my gut
>USB otg (as host?) won't confict.
can you specify the pins for usb and 5v power ?
>As for your other requirements you'll need to find the pinouts of the hardware you're using and check for conflicts.
i thought that the soldering is optional ,but I'll give it a try ,there's guide on the yt
>Does your screen really use all of the GPIO or does it just connect to them? Again, find the pinout.
