Add a USB wifi, then put everything but the laptop on the local wifi.

Although I think you are likely to run into serious issues with 
quality/bandwidth.  Multiple devices streaming at once is likely to run 
into a serious bottleneck.

Using a laptop as a wifi router shouldn't impact it's use for normal 
desktop type apps at all.  It will use a bit more battery/cpu, but not a 
particularly noticeable amount unless you are trying to sleep the laptop.

Ya, that's very unlikely.  Not sure that's even standard functionality 
for most wifi adapters, might well require a non-standard driver for 
your laptops chipset.  I've never setup a linux wifi adapters to be on 
two wireless networks at once.

Ah, that's tricky
