As for the ND sheets, either density should work. The 3 stop material is probably more useful, but with the 1 stop sheet, you can cut multiple pieces and gang them for more density.
I rarely print smaller than 8 x 10. I might need the ND filter if I printed smaller than 5 x 7.
Over time you will probably expose your negatives with more density and solve the problem, or you will discover that your bulb is too bright for some reason causing the issue. Good luck.
