Apart from that, start with something simple like matte top coating some of your snap kits and then maybe try painting something simple. I recommend starting with spray cans at first, painting is not for everyone.
For sanding start with a variety of high and low grain sandpapers and gently work your way up grains on the nub. When you get more advanced I recommend investing in a set of hobby files for sanding as they are a lot more precise.
