Power Strip Question - PLEASE HELP

I need to power my audio system and various electronics from a single duplex outlet. Although this is less than ideal, I need some advice on how to avoid degrading sound quality.

Essentially, I want to buy 2 power strips for the duplex outlet. The first will be used exclusively for my audio system, while the second will be used exclusively for other electronics. Here is the breakdown:

1) Wiremold L10320 Power Strip (9 outlets, 6 foot cord):
- Naim Nait 5i-2 integrated amplifier
- Naim Nait 5i-2 cd player
- Pro-Ject Tube Box II phono pre-amplifier
- Pro-Ject Debut II TT (weak link, I know)

2) XYZ Power Strip:
- Alarm clock
- Phone charger
- External HD
- Laptop computer

My main concern is with the second power strip. I'm worried that these common electronics, being powered on the same line, might degrade the sound quality of my audio system.

Is there any way to limit the interference of these electronics, thus preserving sound quality? For instance, would a power strip with a surge protector limit the interference that these electronics may produce?

If possible, I would like some recommendations for power strips from Allied Electronics, since I will be buying the Wiremold from them (http://www.alliedelec.com/).

I don't have any strict requirements, but I would prefer an inexpensive unit (<$10, if possible) with a short cord.

Thank you so much for the help!
