most alarms are compatible with your car. as for the windows, if you are talking about sensors, most alarms come with shock sensors and no glass break sensors. shock sensors are sufficient in detecting the vibration caused by breaking a window. if you want the windows to go up and down, then you need to get a seperate module(more $$$$). visit www.the12volt.com for some alarm basics. as for the door locks, your locks are negative trigger(they get activated when a ground pulse is applied to the unlock and lock wires). as for alarms, ebay i think has some cheap ones. also, circuit city used to have do it yourself alarms so check them out.
