Yes, you could use either. RCAs (analog) will only give you 2 ch. stereo. The optical may or may not output 5.1 audio and this is an issue you'll run into with any soundbar, not just the Sony. Many TVs only output 2 ch. via optical from components connected to the TV with HDMI, however some TVs will output 5.1 from some or all components.
If you get the Sony you could first try just connecting optical from the TV to the CT350 and see what you're getting from each component. If you get 5.1 across the board, you're good to go. If not, there are options.
If you can't get 5.1 from the PS3, move it to connect directly to the CT and then connect HDMI from CT to the HDMI port you were using for the PS3. You'll still have your video setting and you'll have 5.1 audio direct to the CT.
If the other two components have optical out, you can run optical to the CT in addition to their HDMI connection to the TV. You'll need to change audio settings on those components to disable HDMI audio.
Obviously these options make using more than one remote necessary so you may want to add a Harmony to your budget.
