Don't bother with a monitor for the rpi.  Use ssh to connect to the rpi and work that way. 
Simply connect the rpi to the network, and use something like putty to connect to it through ssh using the ip address it gets assigned from your router.
If you don't know how to compile and run the miner software on an rpi, there are a lot of guides out there.  If I have time I can write something up.
