Car Alarms: Viper 5901 install for a 2008 Dodge Ram 2500, dodge ram 2500, 2008 dodge ram 2500

Question
I am going to purchase the viper 5901 for my 2008 Dodge Ram 2500 Quadcab, 6.7 diesel, auto tranny, all electric (Including back glass).  I have been doing online research for about a week now.  Would like to know any pointers that you guys have and also which module should i buy.  Found the DB-All xpresskit module, looks like it has the most functions? Any comments on that.  Obviously I'd like the install to have as many plug and play options as possible.  Can't find the req'd wiring diagram for the vehicle either, so finding the wire's is sure to take quite a bit of time.  I would like to have all the functions available.  Any help will be greatly appreciated, including who is a good reputable place to purchase the alarm from.

Thanks in advance
