Great questions! It makes me sad that this post sat unanswered on a "fitness" forum for eight days, meanwhile the whirlwind RealTroll deluge continued unabated as usual in countless other threads!
Based on my own experience, I don't think you have anything to worry about in terms of your liver or kidneys based on what you are taking. I think it actually looks really good. Because good nutrition helps everything, your vitamin and mineral supplements can only have a positive effect -- provided they are not in excess. You need to worry about an excess of all the vitamins and minerals except Vitamin C and (for the most part) the B vitamins. That said, it's a complicated issue, since the recommended daily allowances are sometimes possibly too low to provide an optimal dose.
Personally, I would consider supplementing with copper and magnesium in addition to what you are already doing. Copper, that is, since you are taking zinc in addition to your multivitamin/mineral. (http://www.bodybio.com/content.aspx?page=mineral-balance-copper-zinc
) Magnesium, especially if you are getting a lot of calcium from your supplements and food and whey protein intake. Magnesium helps the body properly regulate calcium and has other benefits. Around half of the U.S. population is deficient in magnesium. Also, don't forget good old iodized salt -- it's essential, too (especially important if you are sweating a lot during your workouts).
The only thing in your diet and supplement program that is a potential cause for concern, in my opinion, would be excess calcium. I'd add up how much calcium you are getting daily from your protein and other supplements and keep an eye on other sources of calcium in your diet as well. I don't think it's much of a worry, but I'd always try to keep calcium at or near the recommended daily allowance. Too much of it, like many things, can cause kidney problems.
I do think, however, that you should get most (maybe better, all) of your protein from meat, poultry, eggs and seafood, rather than dairy (whey protein is from milk). I would not, however, use protein shakes as meal replacements or exceed 50 grams of whey protein per day (http://www.mayoclinic.org/drugs-supplements/whey-protein/safety/hrb-20060532).
It couldn't hurt to take occasionally a little milk thistle for your liver health and some cranberry supplement or cranberry juice for your kidneys, though I don't think you need it more than the average person. Your doctor can test your blood to see if there is anything wrong. If you do have your blood tested, stop taking creatine a week before the test, as creatine can distort the results. It is a good idea to have your doctor test your blood occasionally to make sure the basics are in order.
Needless to say, stay off the juice (steroids). That will definitely hurt your kidneys, liver and a lot more (like your testes). (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4515889/
