Understanding affiliate program to follow

I Run a website with 30 respondents. Each post member
Article her page every day. 30 new pages per day on the whole.

I investigated the idea of adding the affiliate accounts with Amazon,
Cj.com AdSense and LinkShare. This is to pay my bills, so the money
I go, that the respondents, with advantage to the respondents
do best.

I understand that pay all the affiliate programs on performance.
My questions:

1. The master account on the distinction between the 30
result the percentage of respondents purchases? In other words,
I track the sales page coming from? Can I track day? It would be
by email or complete.

2. Otherwise, it means that I mean I open the 30
accounts? Does the site allow me to do? What happens if he or 300
I had 30,000 pages to keep?

3. Is third party software (for example, would adsensetracker.com)
help with the tracking?

Overview of the answer would be the best indication of other programs and
description, with links to the original program docs, how to establish the
traceable accounts. Even better, and even a large tip, is
identify the competitors of the programs that actually provide the
I'm looking tracking.
