I would just go with the 35 watt. 55 is way to bright, and if you're not doing a retrofit you will just be scattering light even more so. You don't need the error eliminator, that is for cars with a "burnt out bulb" detection system.
I highly recommend spending a few more dollars and get the hi/low kit, it comes with the relay/wiring harness and everything you need to make it the HID's work without any modifications. I also recommend getting the analog ballasts, I have the digital ballasts in my fogs and they don't always light up when I turn on my lights, I have to flip the switch a second time to get them to work. I have the Hi/Low 6000k kit installed and it was super simple. There's a write up on here that covers everything you need to know to do the install.
