I'm just fighting some stability issues with the serial communications for my Rainbowduino solution, but as far as soldering is concerned you may be able to get away without any as long as you can find a way of connecting the LED strips to the Rainbowduino outputs.
Serial comms is done via a USB Uart connector that plugs into the rainbowduino at one end and a USB cable at the other. I'm powering through a PC power molex, but a JST connector and power supply could be purchased along with the Raunbowbuino from Seeed that would mean no soldering for the power. I'll have a think about how you could go about connecting the LED strips easily without soldering - I'm using the RGB strips from DealExtreme and they come with a connector on the end, so it may be possible to somehow use pin headers to connect these up.

That circuit will just turn the leds on most of the time, what you need to do is pass the vga signals through a lowpass filter, then convert that voltage into a proportional current for the leds.
That being said, you won't get any brightness or color adjustments, which you definitely need, without it most of the video content will look like white light.

How does adjusting the tv's brightness and color change the vga output?

May I ask you what boblight-x11 settings you are using?
