I've been involved in performance testing from the user end, and from the big company end. Often, at the big company end, they decide what sort of results they want, and then design the test around that. The only way to get a reasonable test result from the user end is to write your own test, representative of the work you do. Then, ask the salesguy to run the test, have it run, or allow you to run it.

Your questions can be covered by several books. I will try and answer them briefly.
1) What are the different types of mainframe applications?
I would break it down into to four very general types:
a) Online transaction processing
b) batch processing
3) Database server
4) “New” applications: Web applications, FTP server, Java applications and more

2) What are the general performance issues that are expected?
Usually: CPU , real memory(known as storage on IBM mainframes), I/O.

3) What tools are used in performance testing mainframe applications?
For real time performance , specialized monitors are used. The common ones are Omegamon, RMF,TMON, BMC-Mainview, CA-Sysview and more
For historical performance analysis the above monitors have a historical component. Other specialized tools include CA-MICS and TDS

Hope this helps

Mike
