No problems reviving the thread. The only module I needed to get was the DEI 556U (you can see it here http://www.sonicelectronix.com/item_...U-B-556UW.html). Yes, it's $24.99, and it's used as a transponder bypass to make the vehicle detect a key during remote start.
I did not need any addition modules for door locks or anything else, and certainly nothing for $125.
If it's a 5AT - you're good to go with just that module and it's a fairly straight-forward install. On a 6MT, you'll need to find the P/NP switch at the ECU to ensure you can only remote start when in neutral.
Hopefully this helps.
Edit: didn't see you mentioned a clutch bypass so you're on a 6MT. The clutch bypass is pretty simple, can be done with a relay switch to close the clutch loop during remote start, read KPierson's post above. Make sure you hit the P/NP switch at the ECU so your car doesn't drive away from you when you accidentally remote start in gear.

They probably quoted you a data interface module so they don't have to run wires in to the doors. You can purchase CAN bus based interfaces that drastically reduce the time needed to install a remote start (thus lowering the labor cost). Since these modules are very advanced they do cost more. Most of them will do transponder bypasses as well (so that $25 piece wouldn't be needed if you bought the more expensive one) and most of them do NOT require you to keep a key in the car.
For only $200 for labor I seriously doubt they are planning on taking the time to run wires in to the drivers door. If you go back to that shop and tell them you want it all hardwired I would expect that quote to go up at least $50-100. The main drawback to using a CAN bus module is I have yet to see one that will allow you to raise and lower the windows with the aftermarket remote (and no added parts). If you run the lock/unlock wires directly to the drivers door you can control the windows by extending the pulse on the respective wire.
