According to the requirements you said you were given you cannot answer the questions you posted. The only requirement was that the server could handle 50 users. If it did that then it passed. Now if you go back and tell management this they will think everything is fine and their site is spectacular, so I do not suggest you do that.
What I would suggest you do is tell them you were able to get 50 users on the system BUT CPU utilization was X and memory was Y and etc etc etc. I would also try and educate them on requirements needed to perform valid tests. You need to tell them the kind of information they need to provide you.
We habdle this problem with using their own language. We go after a business case, or question they need answered. Then we ask them what the qualifications are (AKA requirements for a successful test) and get back ground data on customer impact ect. This approach seems to work a lot better than the old one which was telling them we cannot test without any requirements, but the still asked for tests and gave us no requirements.
Re: How will u decide performance criteria in loadrunner

Create a test plan. Define some scenarios. Define a
pass fail criteria. Provide copies of test plan to
all interested parties. Solicit comments. In the
absence of any feedback execute your test paln and
report results accordingly.
When it all hits the fan refer to original test plan.
