Is anyone familiar with muscle mass (body muscle) percentages, and what is an ideal, fit, athletic, etc etc value?
For example .. in regard to body fat percentage .. for males: 8-13% = Athlete, 14-17% = Fitness, 18-25% = Average.
I have no clue about the muscle mass percentage though, and can't find it anywhere.
Little help?
It's the same here mate. I've been looking up on the subject for the last 8 years or so and still coming up with nothing. It's very difficult to map the human body in terms of muscle mass because you also got to consider all your tendons and ligaments, etc. There have been two studies I found that are similar to what you are looking for.

How do you work out your body fat percentage?
There are several ways but they all cost money and some are not quite as accurate and require several visits. Most are offered by professional fitness centres and some hospitals.
1.THE PINCH TEST
Special calipers are used to measure folds of skin around specific spots on the body. This is not a precise method; but it is relatively accurate if a training professional conducts the test. Unfortunately, there is a variety of formulas that can be used to estimated body fat and quite often it is performed slightly different by each person. Thus, to increase accuracy, always have the same individual perform your pinch test . Also, always remember, the pinch test is not an exact measure of your real body fat percentage , but can work wonderfully for a monthly reference to monitor your progress. You can buy calipers yourself from several stores but they can be a bit expensive.
Accuracy: Moderately accurate when conducted by a trained professional.
2.BIOELECTRICAL IMPEDANCE TEST
A trained technician connects electrodes to your hand and foot while you lie down. Then a harmless radio-frequency pulse is run directly through the body to measure water content. That number provides a estimate of body fat with an error of 2 or 2 1/2 percentage points. Although, exercise and different levels of liquid intake directly before the test can distort results.
Accuracy: Equal to the pinch test
3.IMMERSION TEST
This is by far the most accurate body fat measurement method available. The test requires you to exhale the air from your lungs as you get dunked into a pool of water. The method only has an error margin of 1 body fat percentage point.
Accuracy: The very best
4.BOD POD
You step into an egg-shaped chamber, sit for 20 seconds, and that's it. The chamber measures air displacement within your body. This measurement is converted to your relative body fat after your weight is factored in.
Accuracy: Initial tests show that it's as good as immersion.
There's also the scales that Justin mentioned. I've never used these before because I'm not sure how accurate they are.
