Answer 1

Connection from R/3 to XI  
You have to two create RFC destination (TCP/IP) LCRSAPRFC and SAPSLDAPI for the SLD connection.
Program ID will be
LCRSAPRFC_<PID>or<XID> depends on your XI Box for RFC destination LCRSAPRFC
and same for the next connection (SAPSLDAPI_<PID> or <XID>
Note: make sure you give the gateway host and gateway service of the XI sytem but not the R/3 sytem. The details you can find with TX-SMGW on the xi system.
Before testing these connections login to the VA tool on the XI system and create these destination under JCO RFC Provider and under repository make sure that you give the host name of the R/3 system as you have created the RFC connection on the R/3 server.
once these connections are successful, go with the TX-SLDAPICUST on the R/3 system and there the R/3 system should point to the XI SLD.
Go to RZ70 and run the data suppliers and register the R/3 system in the SLD
USE TCode SLDAPICUST and maintain the necessary information like Host, Port.
for RFC LCRSAPRFC and SAPSLDAPI...you hve to create this as TCPIP with PID...to find the appropriate PID for these...try to find out from the basis what they have maintained in the visual admin
login to Visual admin...click on servers....JCO connections there what is the name of the LCRSAPRFC and SAPSLDAPI use the same name...if you are not sure of this ask the basis to give exact name
once you do this run the TCODE SLDCHECK it shouls login to SLD...check SPROXY then
If you are doing the IDOC communication from R/3 to XI means
