Help with Raspberry pi

W7NIK

Node red  Control panel. or any panel that  has all the control on one panel.
I have following system ,
flex 6500 networked, 
SPE 1k-FA amp , 
ERC usb rotor control ,
Wavenode sensors, USB  for amp input and out put.
Kmtronic Udp relay. for remote antenna switch and FLex, amp remote start .
Steppir sda100 controller FTDI USB 
Windows 10 computer 
Software ,  PSTRotator AZ Wavenode,  N1MM,  FRS stacks . 

I am looking for a Raspberry Pi board that  i can connect to my network.  I am not sure what to buy?
 First question , can I view the wave node sensors without running the software .
Second question, Easy Rotor  Control boards  can be controlled? USB  connection.
Third,  What type of operating system do I install on the Raspberry PI ?  Can i just locally remote into and control the station via  Raspberry PI board . 
If the out puts are USB on a windows 10 computer how does the NODE red  raspberry pi  connect to the devices? 
Am I just wasting my time  if everything is not LAN based connections. 
Do I connect all my USB FTDI stuff to the raspberry PI ?
Right now i have click on many programs to work everything FRS stacks has missing things like the  HOME  button  when i am on 80m /160 m
Frs stack has  no relay controls, i would have to  enter IP address and UDP command . 
please  send me some ideas, .
