Those bench marks do not mean anything. Your progress is five pounds on the bar each time, and the process (of both training and nutrition) is the same until that changes.
Benchmarks based on bodyweight are relatively useless for someone in your position, because in all likelihood you can't gain a great deal of strength at this bodyweight.
Good on you for recognizing you need to be serious about nutrition. You are underweight for the purposes of this program. Start thinking of yourself as a 200 pound man, since that's where you need to get to. For starters, at least.
