custom car security to a newb

hello, ive never owned a car alarm but ive installed a few of the wallmart ones. I am building a new truck from the frame up and want to get a security system that has an engine cut off, gps tracking, and separate detection for glass breakage. I also want to be able to program custom voice alerts for when the truck gets hit on the outside or undercarriage while parked. the truck will be a 98-02 2500 I6 dodge ram. I want to be able to access GPS data and shut off control from my own home computer and i also want to install a remote actuator to deploy CS gas in the cab if a window is broken while the truck is off. what type of system do you recommend for these features? thanks.

has anyone used the galaxy 500? im looking to know how well it works and if anyone has had any issues with them. im installing it into a 01 2500 dodge ram. http://www.slickcar.com/productdetails.asp?Productid=41471 thanks
