Good comments by the others. I agree that two lines should be adequate for your relatively low powered system. I would add that experimentation with what components are plugged into which line could very well be worthwhile. And it is even conceivable that you could find that best results are obtained with the entire system connected to just one of the dedicated lines.
I say that because while on the one hand connecting power amplifiers and digital components to a separate line from the one powering components that generate or process low level analog signals can minimize coupling of electrical noise from the former to the latter, a tradeoff may come into play, depending on various factors such as the internal grounding configuration of the specific components. The tradeoff being the possibility of increased susceptibility to ground loop issues, especially if the connections between components that are on different dedicated lines are single-ended (utilizing RCA connectors) as opposed to balanced (utilizing XLR connectors).
If those interconnections involve analog signals, the symptoms of ground loop issues would be either low frequency hum or high frequency buzz, or both. If those interconnections involve digital signals, the symptoms would be more difficult to predict or identify, but may involve a general reduction in clarity, to an unpredictable degree.
As far as surge suppressors are concerned, for optimal protection you should have one for each dedicated line. Again there is a possible tradeoff, however, as some people find that sonics benefit from having their power amplifier plugged directly into the wall, with no surge protection or power conditioning.
I and a number of other members use this $259 8-outlet BrickWall surge suppressor/line filter with excellent results. Note that it provides some degree of noise filtering between each of its four duplex outlets, as well as between those outlets and the incoming AC.
