Development time for the prints? I thought you were never supposed to "snatch" prints. Aperture of enlarging lens won't make a difference in contrast, surely? Stopping down further probably won't improve sharpness either, I read in a few books that 2 or 3 stops down from max aperture is best sharpness. I did some 9x12.5 prints at different aperture settings to test and my CE-Rokkor 50/2.8 seems to follow that rule (best sharpness at f5.6 or f8, can't really tell the difference).
When I was buying my enlarger, I almost bought a colour-head model. I opted to get a normal old-fashioned B&W head model instead (a Durst M609), because I was told that not only is it difficult to accurately calibrate the colour values to a contrast grade, and they can wander quite a lot depending on temp and age etc (even the paper you're printing on to)., but that you simply don't have the range of contrast control compared to a book of Ilford MG filters.
My book of filters goes from 00 to 5, I think. Is it possible to set your enlarger to white light only and borrow somebody's filters? I assume even a colour-head still has a filter drawer.
