Lots of different ways to go about it.
If you are using a stock 2004 PCM it will work for control of the 4L80E with proper tuning and wiring. Otherwise it can be controlled using a standalone controller like the Optishift.

Crossmember will likely need to be fabbed but there may be something out there already made.

Speedo can be handled with a mechanical speedo tailhousing add-on, or by using an electronic speedometer if not using stock gauges.
