I have a couple data sets with these files (image 1). When I load the symbology, I get random colors (image 2). The public domain I downloaded the files from have a predefined symbology (image 3), is there anyway I can load it?

In general you should look at this page of the APIs documentation. As a working example see as follows:
vl = iface.activeLayer()
## get default style
myStyle = QgsStyleV2().defaultStyle()
## get a list of default color ramps [u'Blues', u'BrBG', u'BuGn'....]
defaultColorRampNames = myStyle.colorRampNames()
## setting ramp to Blues, first index of defaultColorRampNames
ramp = myStyle.colorRamp(defaultColorRampNames[0])
# set up an empty categorized renderer and assign the color ramp
renderer = QgsCategorizedSymbolRendererV2(field, [])
renderer.setSourceColorRamp(ramp)
vl.setRendererV2(renderer)
I have been searching within the Noun Project open source icon library and found some useful images. Some of these may work better than others when resized for mapping. They are all under a Creative Commons licence.

In QGIS, add an ArcGIS REST Server Connection using the following URL:
https://gis.saskatchewan.ca/arcgis/rest/services/Economy/P_1_250000_Scale_Geology/MapServer
Add the vector layer
250K Bedrock GeologyRight click on the layer in the layers widget -> Export -> Save as QGIS Layer Style File... -> save the symbology as QML file.
You could try to apply this QML file to your downloaded data (right click on the layer in the layers widget -> Symbology -> Style -> Load style...)
