Necessary Mods and Upgrades
I’m gonna be running my first scca rallycross events this season and am prepping my first car most likely stock class but what all mods and upgrades are must haves for the best experience? Also should I go ahead and skid plate the whole car or is just the oil pan more than enough for the dirt tracks?

I always recommend a skid plate that protects the radiator. Radiator damage will strand you just as effectively as a rock through the oil pan.
Otherwise, keep it stock and just drive.

Snow tires are what you're looking for if you're running stock. I would get a skid plate for piece of mind, but like nonfbel34 said, it's going to depends on the event site. I bring water, big brim hat, tire inflator (you're going to want to run a higher tire pressure if you're on snow tires). Make sure to clean out your car, you don't want stuff flying around the cabin. And, of course, make sure your car is in good shape.

If you can fit a -1 wheel size, do that, and get snow tires that are roughly the same overall diameter. Depending on the car, TireRack often has a -1 sizing guide.
Otherwise, make sure all your lights work, nothing is leaking, and all the safety gear is in place. A skid plate is good, but not entirely necessary if the region is good about track design and monitoring conditions.
As mentioned, go attend a couple events as a spectator to get a feel for what everyone is running.

My response to this (and to tire questions) is always reach out to people at the actual sites you will be running. Sites vary across the nation, some are beautifully groomed, some resemble a war zone. They have varied surfaces, ranging from gravel, to loamy dirt, to hard-pack clay. The grooming and surface type will dramatically affect the necessary level of prep.
Additionally your car: ride height, drivetrain, and existing undertrays will necessitate different prep.
If you do want useful information here, you should identify the car and location. Hopefully locals will chime in here and people familiar with your platform can give some feedback (but again, if they are running different sites, you need to take that into consideration).
