First steps on new homestead

My wife and I are closing on a property soon that we intend to turn into a long-term homestead for ourselves and our kids! We are very excited and also overwhelmed with the possibilities and what to do next. I have just finished using the web soil survey and have no idea how to read the legend. It states:

BkB Berks channery silt loam, 3 to 8 percent slopes 8.2 22.1%
BrA Brinkerton silt loam, 0 to 3 percent slopes 10.4 28.0%
CtB Clearbrook channery silt loam, 0 to 8 percent slopes 11.3 30.4%
Ma Markes channery silt loam, 0 to 8 percent slopes 0.2 0.5%
WeB Weikert channery silt loam, 3 to 8 percent slopes 7.0 18.9%

Could someone please help me decipher this. We are trying to plan what trees we will plant and where on the site. It is 13 acres that we presume was being used mostly for hay (this we are unsure of and are trying to figure out some more history).

Any other things I should be checking on before closing to best prepare for our first few months on the property? We close in August, so we can hopefully get some trees planted this fall.

Thanks!
