Gentlemen, gentlemen, I have done much research and installed the perfect set while the best priced also. For the in-dash kit you'll want to go with the Scosche
TA2053B 2005 - Up Toyota Tacoma Double DIN Installation Kit (Factory Color Matched Silver). They also have a single DIN as well. The Silver is damn near dead-on but it doesn't have the raised bumps like the original. Not that big a deal though - at least to me. I just care about matching.
Regarding subs; Scosche also makes a sub enclosure which comes with a 10" EFX sub. The enclosure has matching plastic to the storage compartment plastic and, best of all, it just drops in. No cutting or anything. I got it for $199 off of ebay
and the DIN kit was $25. You are just left to get an amp which you can put under the seat. Here are some pics:
