Sorry about the late reply,
I would suggest that if you have an extra few hundred dollars, I would pick a power conditioner up. Keep in mind that a power conditioner is like high end cables. A cheap one will always work, but a good one might work better.
Monster power bars use "Clean power" that filters out very low amplitude spikes in voltage (talking about mV). This might help clear up some noise in the screen. But just like high end cables, is there really any EM interferance to protect against? Maybe not, but it will never hurt.
Monster (and other brands) also make better devices that can acually regulate the voltage (a couple of volts) coming out of the wall. This can be handy if you area is subject to brown-outs, or small power surges.
The question of you needing one might just depend of you current situation. for myself, I live in an old house with poor wiring. Before, when I turrned of the vacuum, I saw interferance on my TV. Since hooking up a Monster clean power center there is no more interferance.
Keep in mind too, that an interferance problem can also be caused by other things (like your amp -this is the purpose behind a stage one and stage two power center) or you could have a ground loop problem (different solution required.)
You should always have some sort of surge protection because you don't ever want to have to buy a new TV if lightening hits the city power tranformer down the block.
