Or Should I Just Send It To Speartech???

If you are "very good with electrical" why are you asking such a vague question? And why would you send it to speartech if you are so good?

because i dont know where to even begin on where to hook the gauges up and such and i cant find a good diagram of the wiring harness

For a project like that I would get a Helms manual set for your vehicle.

you need to run new sending units for oil and temp, you can't just tap the old senders. For tach and speedo, there are outputs on the PCM--no idea which pins on a truck PCM, go look at the wiring diagram for the donor vehicle.

Take a look at C2-10 for "RPM OUT" and C2-50 for "VSS OUT". That's what I found in 5 minutes of looking at an '01 Silverado 5.3 diagram--dunno if your '03 Av is the same.
