Jon,
On lowering the contrast of your palladium print:
I've found ammonium citrate developer to give higher contrast prints than
potassium oxalate developer. Likely your sodium citrate is similar to
ammonium citrate though I haven't tried it specifically. But the standard
potassium oxalate developer may be worth a try.
