You would still need a launcher but like in MIUI Android ROMs, it's like an iPhone type launcher with no app drawer.
Those apps should work fine. If you have change your screens density or edited device name in build.prop, that could tell play store that your device is not what it is. I installed Fast Burst Camera on a friends phone and it worked really well, has zero shutter lag.
WiFi still turns off I find when I set it to always, I think it might be kernel related. You can also change the driver for MTP to mass storage in device manager on PC. MTP is slow for transferring data compare to mass storage probably because it wasn't designed for an SD card.

WiFi works fine for me, even with screen off. And... WHAT?! How can you change it to mass storage? Ive been struggling with this since I came to ViperS 3 and Ive slowly accepted, that there is nothing I can do. Is there any guide? link to drivers please?
