Steps to connect XI with other systems

Question

Hi all,
What are the steps to be followed in general to connect a SAP system with a third party system using XI. It will be more helpful if I get information on the settings needed to be done on the 3 systems to get integrated (SAP,XI,Third party system).
I listed down the settings needed to be done in each of the system as far as I know. Correct/Update the list if you know more.
<u>SAP system:</u>
RFC destination from SAP --> XI
<u>XI system:</u>
WEB AS ABAP technical system in SLD
Third party system in SLD
Do we need a RFC destination from XI --> SAP?
Apart from the above, do we need to maintain any settings in XI(both ABAP and JAVA stack) and the ERP system.
Also, let me know what are the parameters(like host name,client) needed if a system is going to integrate with XI.
Your help will be appreciated
Regards,
Sakthi
