On the outside you should have a perimiter drain at the footing level or at least below the the dirt level inside. There should be 6" to 8" of concrete or wall above the dirt outside and the landscape should slope away from the house. Insulating the floor with fiberglass would have worked if the space was vented from the outside but the solid surface should not have been there.
Doing anything on the inside before fixing the outside may not be productive.

I would do that first and maybe alot of moisture would not be in the crawl space. The insulation above the foam will be a problem and should be replaced and held in place with some more like chicken wire fencing so you have air movement below and then I would just knock out a couple concrete blocks and poly the floor.

Depending on how much your labor is worth, you may want to price out a humidistat and a fan. Two Air Changes per Hour is one benchmark figure for pulling in outside air.

Is there a proper way to slope the landscape or do I just slope the landscape? Yesterday I fix4ed the gutters and sloped the landscape a little but I wasn't sure how high and the grading it should be. Its been raining all morning here, I'm going to check it when i get home.

Making sure the water gets away from the house is all you really need. After a good rain dig a few holes next to foundation, dirt should be dry. It is important to have 6 to 8 inches of wall showing on the outside. The wall will wick water up and it needs to air dry at the top. If you can not get the dirt to stay dry you will have to think about perimiter drain on the outside.

There is about 2 feet or so of brick showing on the outside, ill post a pic later today. How big of a job is it to install a perimeter drain?

You would like to put the drain at the level of the footing or at least well below the level of the dirt inside. Perferated pipe around the outside and run down hill to city storm or daylite or sump pump it out. So it would be a little digging a little hauling gravel to cover the pipe, filter cloth to cover that and backfill. If you do go to all that you may as well waterproof the wall with a tar like product up to landscape level.
Sounds easy if you say it fast.
