Your question is a little confusing as it is landlord's that file unlawful detainer complaints and it is the landlord that serves and files the Request to Set Case for Trial. Assuming the landlord served that on you, that means the Court will be setting a trial date assuming everything is in order and sending you and the landlord a notice by mail as to when the trial will be set. So what you were told is generally right and you can wait for the Court to let you know when the trial is.
Getting an attorney will be helpful if you can afford one.

This answer does not create an attorney-client relationship.
Your trial will be held in Van Nuys. In most courts, you can file a "Counter-Request to Set Case for Trial," but in Van Nuys, they just set a trial when the first request comes in, so there's no need to file a counter-request. If you want a JURY TRIAL, be sure to post fees of $150 five days before the trial date.
I second the idea that you retain an attorney to represent you.
