If the chemistry mix starts getting "tired", a few drops of 3% Hydrogen Peroxide can extend its life and get the contrast back to what it was - without using Chromates or other toxic chemicals which are difficult to buy in Norway.
A cheap cooking brush ( 5 for NOK 10) is my favorite way of spreading the chemicals. Discard when it gives uneven coating - I'm on my third brush now. I'll have to buy another pack next year, if I can find it...
Your puddle pusher is longer than I would prefer for 4x5" and 5x7" prints - and for 8x10" paper.
Sodium thiosulfate for fixing.
Ammonium thiosulfate, or very very dilute rapid fix for clearing highlights.
Tetenal gold toner is good, and lasts a long time. If you want to gold tone - it's not strictly necessary. KRST (IMO) is worse than useless at the extremely low concentrations needed - unless you want the print bleached at the same time as toning. I know others swear by it, so far I have only sworn at it.
