That's a tall order. CICS is not trivial.
My best suggestion is to start with the IBM CICS programmer documentation, namely SC34-7022 (the CICS Programmer's Guide) and SC34-7023 (the CICS Programmer's Reference). Those can be found in various forms on IBM's site; search for the publication numbers.
Besides that, there are any number of web pages dealing with CICS basics, though I'm not aware of a good, well-rounded tutorial.
Note that in order to use CICS with Visual COBOL you'll need either Enterprise Server or Enterprise Server for .NET.
