I am curious to know what symptoms you may have, if any, and when you were diagnosed. In terms of severity, a diagnosis of first degree spondylolisthesis is the least severe and there are probably plenty of people walking around, and lifting with, this type of pathology without even knowing it.
With that being said, it doesn't mean that it can't get worse. Performing the basic structural lifts such as squats and deadlifts should be fine and in fact can be helpful if you are careful to use proper technique. Remember that you will have less room for error when it comes to poor form on the lifts than the average trainee and that even slight breakdowns could lead to an exacerbation of your symptoms. I would also keep in mind that when dealing with spondylolisthesis lumbar hyper-extension can be just as damaging as flexion. Also, I would avoid exercises such as sit-ups and back extensions in your programming or anything else that involves repeated lumbar flexion/extension cycles.
I hope this helps.
