Hi, LaTeX is a program to »typeset beautiful books«. If you are having math in your document, LaTeX is
the way to go. There are many more ways to get done what you want, but if there is any possibility that you have to do something like that again, use LaTeX. There is not only package pstricks, but also pgf. You can see some examples at
TeXample and
PsTricks.net.
You will need some time to learn, but it's time well invested.
The output of LaTeX is either dvi or pdf. You can convert dvi to pdf, and this should be compatible with illustrator
You can install LaTeX by installing TeX Live from
TUG.
Additional hint: Click on »Open in writelatex« to compile the code of Crazyhorse.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.
