Which Crutchfield steering wheel control kit do I get?

Getting a Taco tomorrow, it's an '06. My first concern is the lack of an auxiliary port, so a headunit is my first go-to. I couldn't find any info on this from searching the forum or Google.

Crutchfield lists two different steering wheel control kits at checkout. They don't do a good job explaining the differences, but I did specify my model is without a JBL stereo. I just want to be sure, and minimize effort during this installation.

One is a combination of these three wire sets:

• $8 Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker
  Metra 70-1761
• Metra
  $63 ASWC-1 Steering Wheel Control Interface
  ASWC-1
• $15 Metra 70-8114 Metra Toyota 20-pin Steering Wheel Control Add-on Harness with RCA
  Metra 70-8114

The other is a combined kit:

• PAC RP4.2-TY11

For the combined kit, in the description, it says it's for retaining the JBL stereo. Do you need to have the JBL stereo for it? Is it basically a universal set for multiple models to reduce headache? I'm too impatient to wait for Crutchfield's business hours. I'm excited.
