EWM-TM integration

Hi,

I am new in EWM and experienced in SAP TM.

a)As of now we have installed TM,EWM in the same server and hence was wondering to connect between this 2 system , do we still require RFC.

b) How will CIFing work across these 2 system in same client.

c)Thirdly  in the server we dont have the std integration content available for TM-EWM i.e warehouse 0001 is missing.In this case to set up std scenario can the experts share the config guide
