PERM - Labor Certification

Here is a set of questions posed to me recently by one of our clients:

I am Mr. Jones, the employer. The employee, Mr. Smith, is no longer employed with us because of company's budget issue. However, we may hire him in the near future if circumstance changes.

My question:
Q1. Do we need to withdraw PERM LC for him that was submitted 2009?
The status is still in process now. I would like to know if this PERM LC still has any goods for him. Let me know the pros & cons between withdraw it and not withdraw it.

Q. Now that I received my GC through employment, does my employer need to change my position to the one filed in the Labor Certification?
