The Bose does has an Optical input, so that will take care of the audio. However, as far as video goes, the Bose will only do as high as S-Video. It will take component video as an input, but only with an adapter that turns it into S-Video. I would personally suggest that you sell the Bose system on ebay and opt for some seperate components, but that's up to you. However, with the Bose system, you will not be able to take advantage of HDMI because, to my knowledge, it does not have 12v signal outputs to operate a switcher.
