Lots of ways to go.
You might buy a fancy soundcard for the PC. The all have mic inputs. External with USB output.
The preamps you pointed to are overkill, as preamps, I think.
A simple opamp circuit powered by 9 volts will do. An external plug in power supply (wall wort) to power it.
The wireless mic receiver already has mic level controls, does it not. The amp has level controls too, I would think.
A small 2 or 4 input mic mixer would give you future flexibility.
Since you are going to send this to a 1000 watt amp (!) A mixer with a
parametric and graphic equalizer might be a good idea.
1000 watts of feedback is a scary proposition.
I assume the output of the wireless mic reciever is unbalanced. Two 'wire'. Hot and shield.
If you want to build a preamp I think this page might be useful.
