Okay I feel really dumb for asking this but is J.C-1.mol-1 equal to J/C.mol or J/C/mol?

J/C.mol

It is J/C*mol because C-1 = 1/C and mol-1 = 1/mol.

Should work always be found in J or kJ? Or does it matter?

Work is usually in J but if its value is large enough, it can also use kJ.
1 L.atm = 101.325 J. This is the conversion found in the constant and formula sheet.

J.C^-1.mol^-1 = J/C.mol

J/C(mol) - Joules over Celsius times mole(s)
