If two speakers require a minimum of 40w each, will this unit be enough to drive both speakers sufficiently or will there be issues at higher volumes?

There are a lot of variables in that question, but in general, this amp should be alright. If your speakers have inefficient drivers it may get warm or even begin to clip at higher volume levels. In the end, keep your expectations realistic. This is not a high end 200 watt per channel, wired amp. I am running it for my rear stage on a Samsung Blue ray combo and it is plenty loud for a surround channel. Overall a good sounding alternative to running wires. Much better than cheaper models like the Rocketfish brand.

Do I need two receivers to enable a pair (two) of speakers wireless?

No, one receiver can handle two speakers (mine enables the use of both rear speakers).

How long/thick is the power cord for the receiver? The outlet is 5ft below where I want to put the amp and I want to hide the cord in the corner.

The power cord is around 5.9 feet long and the thickness is 3.5mmx1.5mm. So you should be good.

can you run this in your vehicle?

Probably not. The receiver/amp requires 36 VDC which wouldn't normally be available in a vehicle(except maybe an electric car). You could probably rig a voltage regulator for the transmitter that only requires 7.5 VDC @ 1 amp.
