Just a quick thought on the grading problem. I always start at a grade 3 - using RC VC paper - and do a test strip about 2 inches wide. This gives me a good indication of the exposure times and if the grade is to high/low. Sometimes I will choose a grade, do a basic print, then do a grade higher/lower as the wont takes me. It might seem hit and miss but after dry down etc you will be surprised at how you may have misjudged the grade in the first place. Plus it's good experience to look at a print in different grades because after a while you instinctively guess the right one and get it right.
