You are in the right direction with all of this. Things I learned the hard way include - use paper safes - use nitrile glove - test your fixer - don't do marathon printing sessions (quit when you get tired) - Take your time - try several exposure levels before printing a bunch of prints - sometimes 1/3 stop really makes a difference and it is good to choose that darkness or lightness before burning a lot of sheets. - Use oversize print trays - my smallest are 11x14 - better to use more chemistry anyway - if you expose and develop your film for 1.25 densities you will not necessarily need filters.
