I posted a list of supplements in the other supplement thread but you have gotten some good suggestions. Whey protein should be your staple supplement it is the most important. I also suggest BCAA's L-glutamine NO and creatine monohydrate.
Creatine has been shown to be safe, the concern has not been with a persons liver but ones kidneys because the by-product of creatine(break down of) is creatinine(notice the spelling) and the creatinine is filtered by the kidneys.SO the concern is that the excess creatinine is putting extra stress on the kidneys and perhaps longterm could be damaging them. However studies have shown that taking creatine has had no harmful effects on the kidneys.
I hope this helps some, if you have any more questions I can explain what the purpose behind each supplement is.

I would be drinking north of a gallon of water a day.

P.S. IMO No-Shotgun blows no-xplode out of the water.
