Water Reports: What they mean and how they effect our plants?

I was browsing my water report and saw some "nutrients" and other stuff I didn't know. Care to help me out with these figures? I guess what I'm looking for is do I have a lot, too much; I'm looking for a relation of good & bad here.

First, the easy stuff:

Ca: 64.1ppm
Mg: 27.5ppm
Total Organic Carbon: 2.9ppm
Ammonia: 0.421ppm (on average) **How long does it take to get rid of this via plants/biofilter?

From these figures, can anyone tell me how quickly these are used in a high light/CO2 injected tank? Generally speaking. While I'm not really concerned with TOC (or should I be?), how long a supply do I have of Ca & Mg (estimated)?

Other stuff I see in ferts that may/may not have an effect:

Sulphate: 134ppm
Chloride: 150ppm

Is this a lot? What effect does it have on my plants?

What is this?:

Gross Alpha Adjusted: 4.8 pCi/L (from "Erosion of Natural Deposits")
Gross Beta Emitters: 7.4 pCi/L (from "Decay of Natural Manmade Deposits")
Combined Radium: 0.35 pCi/L (from "Erosion of Natural Deposits")

Thanks for any help! I may revise this and send it to my local water co. and see what they turn up as well.
