These ratios should be adjusted for IP, right?

Can you elaborate? I don't understand the context of the question.

When doing player valuation for these categories, do the IP need to be considered to compare the impact of one player vs. the next. Does a K/9 of 10 have a greater impact for a team if it is over 200 innings vs 70 innings; or should it be treated like a counting stat for valuation purposes?

Yes, innings matter. It's not perfect, but I use

((Player ratio) - (baseline ratio)) X IP

Thanks. What is the easiest way to calculate k/9?

There's only one way -- 9 x K / IP
