Compustar Alarm Install... Need help and advice pleeeasee

[BigballinTSX]

I'm getting a supposedly certified compustar dealer to install my alarm.

Now to get it to interface with my car, they want to use the following two things:

Crimestopper CANSL- I belive this is used so that the alarm can interface with the stock alarm, and have it be able to do the trunk relase.

Here's the official discription i found online:
Self Detecting and Self Learning data interface module. New SL technology. One or two wire connection to vehicle depending on whether single or dual wire CAN communication is required. Identifies the doors & trunk status, tachometer (where available), arms & disarms OEM alarm door lock/unlock, sliding doors, trunk and gas cap relase, and heated seats/mirrors and defrost. Easy install cuts installation time in half.

Crimestopper HondaSL- I belive this is what they use to get around the immobilizer that is in our cars.
Here's the official discription i found online: Self detecting and Self learning data interface module. Does not require a key. One module fits all Honda & Acura models from 1998-2006 (except prelude). Only consumes 1.6milliAMP while at rest.

With the addition of these and the alarm, i STILL supposedly will not have the ability to rollup/down my windows with the remote. That will require yet another module attached to the alarm. -- Though I dont think they are aware that the stock alarm has the ability to control the windows (i have the module that KPTechnologies was selling that makes the windows roll up with the stock alarm)-- so maybe with the CANSL (described above) i may not have to buy an additional roll up/down module.

edit: I did some reserach on the forum and the electrical god himself Mr. Peregrine seems to recommend it...

I did want to know about the window up/down thing though... and whether i would NEED that extra module.

And lastly I have read this several times but I just want to confirm, our transmission 6mt Transmission has NO way of sensing that the car is in Neutral correct?

thanks in advance guys!!!
