I am stuck. What is KCL? Is it Kirchoff's Current Law?

Yes.
"a" and "b" are at the same voltage because they are connected together. To work out that voltage you can simplify the circuit and use the potential divider method. There are other ways.
Once you have that voltage you can calculate the currents through all the resistors. Then apply KCL at either a or b.
or you can just wade in and apply KCL from the outset.
